I-viscosity ephansi: I-400 isetshenziselwa ikakhulukazi udaka lokuzilinganisa, kodwa ngokuvamile lingeniswa kwamanye amazwe.
Isizathu: I-viscosity ephansi, ukugcinwa kwamanzi okungekuhle, kodwa izakhiwo zokulinganisa ezinhle, ukuminyana okuphezulu kodaka.
I-viscosity emaphakathi nephansi: I-20000-40000 isetshenziselwa kakhulu ukunamathela kuthayela, i-caulking agent, udaka olulwa nokuqhekeka, udaka oluhlanganisiwe olushisayo, njll.
Izizathu: Ukusebenza kahle, ukungezwa kwamanzi amancane, nokuminyana kodaka oluphezulu.
1. Yiziphi ukusetshenziswa okuyinhloko kwe-hydroxypropyl methylcellulose (HPMC)?
——A: I-HPMC isetshenziswa kakhulu ezintweni zokwakha, okokuhlanganisa, ama-synthetic resin, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni.I-HPMC ingahlukaniswa: Ibanga lokwakha, ibanga lokudla kanye nebanga lezemithi ngokuya ngokusetshenziswa.Njengamanje, imikhiqizo eminingi yasekhaya iyibanga lokwakha.Ebangeni lokwakha, i-putty powder isetshenziswa ngenani elikhulu, cishe i-90% isetshenziselwa i-putty powder, kanti enye isetshenziselwa udaka lukasimende neglue.
2. Zingaki izinhlobo ze-hydroxypropyl methylcellulose (HPMC) ezikhona?Yiziphi ukusetshenziswa kwazo?
——A: I-HPMC ingahlukaniswa ngohlobo olusheshayo kanye nohlobo oluncibilikayo olushisayo.Imikhiqizo esheshayo ihlakazeka ngokushesha emanzini abandayo futhi inyamalale emanzini.Uketshezi alunayo i-viscosity ngalesi sikhathi ngoba i-HPMC ihlakazekile emanzini futhi ayincibiliki ngempela.Ngemuva kwemizuzu emi-2, i-viscosity yoketshezi iyanda kancane kancane futhi kwakheka i-viscous colloid ebonakalayo.Imikhiqizo encibilikayo encibilikayo ingahlakazeka ngokushesha emanzini ashisayo futhi inyamalale emanzini ashisayo lapho ihlangana namanzi abandayo.Lapho izinga lokushisa lehla liye ezingeni lokushisa elithile (umkhiqizo wenkampani yethu ungama-degree Celsius angama-65), i-viscosity ibonakala kancane kuze kube yilapho kwakheka i-viscous colloid esobala.Uhlobo lwe-hot melt lungasetshenziselwa kuphela i-putty powder nodaka.Ku-glue ewuketshezi nopende, i-clumping izokwenzeka futhi ayikwazi ukusetshenziswa.Uhlobo olusheshayo lunohlu olubanzi lwezinhlelo zokusebenza.Ingasetshenziselwa i-putty powder, udaka, iglue ewuketshezi, nopende ngaphandle kokungqubuzana.
3. Yiziphi izindlela zokuncibilika ze-hydroxypropyl methylcellulose (HPMC)?
——Impendulo: Indlela yokuchithwa kwamanzi ashisayo: Njengoba i-HPMC ingancibiliki emanzini ashisayo, i-HPMC ingahlakazwa ngokulinganayo emanzini ashisayo esigabeni sokuqala futhi incibilike ngokushesha ngemva kokupholisa.Izindlela ezimbili ezijwayelekile zichazwe ngezansi:
1) Faka inani elidingekayo lamanzi ashisayo esitsheni bese ushisa kuze kufike ku-70 ℃.Yengeza kancane kancane i-hydroxypropyl methylcellulose ngokunyakazisa kancane.Ekuqaleni i-HPMC intanta phezu kwamanzi, bese kancane kancane yakha udaka, bese ipholisa ngokunyakazisa.
2).Faka i-1/3 noma i-2/3 yenani elidingekayo lamanzi esitsheni, sishise sibe ngu-70 ° C, uhlakaze i-HPMC ngokwendlela ku-1), futhi ulungise udaka lwamanzi ashisayo;bese ufaka inani elisele lamanzi abandayo ku-slurry wamanzi ashisayo.slurry emanzini, gudluza bese upholisa ingxube.
Indlela yokuxuba umpuphu: Xuba i-HPMC powder nenani elikhulu lezinye izinto eziyimpuphu, xuba kahle ne-blender, bese ufaka amanzi ukuze uncibilike.Ngalesi sikhathi, i-HPMC ingahlakazwa futhi ngeke inqwabelane, ngoba kukhona ingcosana kuphela ye-HPMC engxenyeni ngayinye.Ikhona elincane.Impushana iyancibilika ngokushesha lapho ihlangana namanzi.——Abakhiqizi bempuphu nodaka basebenzisa le ndlela.I-Hydroxypropyl methylcellulose (HPMC) isetshenziswa njenge-thickener kanye ne-ejenti egcina amanzi ku-putty powder mortar.
4. Indlela yokwahlulela ikhwalithi ye-hydroxypropyl methylcellulose (HPMC) kalula nangendlela enembile?
——Impendulo: (1) Ubumhlophe: Nakuba ubumhlophe bunganqumi ukuthi i-HPMC kulula yini ukuyisebenzisa, uma izikhanyisi zengezwa phakathi nenqubo yokukhiqiza, izothinta ikhwalithi yayo.Nokho, imikhiqizo eminingi emihle inobumhlophe obuhle.(2) Ukulunga: Ubucwebe be-HPMC ngokuvamile bungamameshi angama-80 kanye nezikhala eziyi-100, ezinezikhala eziyi-120 ziba ngaphansi.Iningi le-HPMC elikhiqizwe e-Hebei linezikhala ezingama-80.Okungcono kakhulu kuba ngcono.(3) Ukudlulisa ukukhanya: Faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukuze wenze i-colloid ekhanyelayo, futhi uhlole ukudluliswa kwayo kokukhanya.Ukuphakama kokudlulisa ukukhanya, kungcono, okubonisa ukuthi kunezinto ezincane ezingancibiliki ngaphakathi.Ukungena komoya kwama-reactor aqondile ngokuvamile kungcono kunama-reactor avundlile, kodwa ngeke kushiwo ukuthi ikhwalithi yama-reactor aqondile ingcono kunaleyo yama-reactor avundlile.Kunezici eziningi ezinquma ikhwalithi yomkhiqizo.(4) Amandla adonsela phansi athize: Lapho amandla adonsela phansi athile emakhulu futhi esindayo, kuba ngcono.Amandla adonsela phansi athile ngokuvamile abangelwa okuqukethwe okuphezulu kwe-hydroxypropyl kuwo.Ukuphakama kokuqukethwe kwe-hydroxypropyl, kuba ngcono ukugcinwa kwamanzi.
5. Iyini isilinganiso se-hydroxypropyl methylcellulose (HPMC) ku-putty powder?
——Impendulo: Umthamo we-HPMC ekusebenzeni kwangempela uyahlukahluka kuye ngesimo sezulu, izinga lokushisa, izinga le-calcium yomlotha wendawo, kanye nefomula yokufaka.ty powder kanye “nekhwalithi edingwa yikhasimende”.Ngokuvamile, kuphakathi kuka-4kg no-5kg.Isibonelo, iningi le-putty powder e-Beijing liyi-5 kg;impushana eningi eGuizhou ingu-5 kg ehlobo no-4.5 kg ebusika;
6. Iyiphi i-viscosity efanele ye-hydroxypropyl methylcellulose (HPMC)?
——Impendulo: I-putty powder ngokuvamile ibiza ama-yuan angu-100,000, kanti udaka ludinga ngaphezulu, ngakho-ke ama-yuan angu-150,000 anele.Futhi umsebenzi obaluleke kakhulu we-HPMC ukugcinwa kwamanzi, okulandelwa ukujiya.Ku-putty powder, inqobo nje uma inokugcinwa kwamanzi okuhle kanye ne-viscosity ephansi (70,000-80,000), kulungile.Yiqiniso, ukuphakama kwe-viscosity, kungcono ukugcinwa kwamanzi okuhlobene.Lapho i-viscosity idlula i-100,000, i-viscosity inethonya elincane ekugcineni kwamanzi.
7. Yiziphi izinkomba zobuchwepheshe eziyinhloko ze-hydroxypropyl methylcellulose (HPMC)?
——A: Okuqukethwe kwe-Hydroxypropyl kanye ne-viscosity, abasebenzisi abaningi bakhathazekile ngalezi zinkomba ezimbili.Ukuphakama kokuqukethwe kwe-hydroxypropyl, kuba ngcono ukugcinwa kwamanzi.Nge-viscosity ephezulu, ukugcinwa kwamanzi kuqhathaniswa (hhayi ngokuphelele) kungcono, futhi nge-viscosity ephezulu, kusetshenziswe kangcono odakeni lukasimende.
8. Yiziphi izinto zokusetshenziswa eziyinhloko ze-hydroxypropyl methylcellulose (HPMC)?
—— A: Izinto zokusetshenziswa eziyinhloko ze-hydroxypropyl methylcellulose (HPMC): ukotini ocolisisiwe, i-methyl chloride, i-propylene oxide, ezinye izinto zokusetshenziswa zihlanganisa i-caustic soda, i-asidi, i-toluene, i-isopropyl alcohol, njll.
9. Iyiphi indima eyinhloko ye-HPMC ekusetshenzisweni kwe-putty powder?Ingabe inawo umphumela wamakhemikhali?
——Impendulo: I-HPMC inemisebenzi emithathu emikhulu yokujiya, ukugcinwa kwamanzi nokwakha kumpushana oyimpuphu.Ukuqina: I-Cellulose ingajiya ukumiswa, igcine iyunifomu yesixazululo futhi imelane nokuwohloka.Ukugcinwa kwamanzi: Yenza i-putty powder yome kancane futhi usize ukusabela kwe-calcium empunga ngaphansi kwesenzo samanzi.Ukwakhiwa: I-Cellulose inomphumela wokugcoba futhi ingenza i-putty powder ibe nokusebenza okuhle.I-HPMC ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali futhi idlala indima yokusiza kuphela.Lapho i-putty powder yengezwa emanzini futhi isetshenziswa odongeni, ukusabela kwamakhemikhali kuzokwenzeka.Njengoba kwakhiwa into entsha, i-putty powder esodongeni ikhishwa odongeni futhi igaywe ibe yimpushana ngaphambi kokusetshenziswa.Lokhu akusebenzi ngoba into entsha (i-calcium carbonate) yenziwe.) phezulu.Izingxenye eziyinhloko zempushana ye-calcium empunga yilezi: ingxube ye-Ca(OH)2, i-CaO nenani elincane le-CaCO3, i-CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Gray calcium incibilika emanzini nasemoyeni i-CO2 Ngaphansi kwesenzo se-calcium carbonate, i-HPMC igcina amanzi kuphela futhi isize i-calcium empunga ukuthi yenze kangcono, futhi ayihlanganyeli kunoma yikuphi ukusabela ngokwayo.
10. I-HPMC iyi-ether ye-cellulose engeyona i-ionic, ngakho-ke yini engeyona i-ionic?
A: Ngokwemigomo ye-layman, okungezona ama-ion yizinto ezingafaki ioni emanzini.I-ionization inqubo lapho ama-electrolyte ahlukana khona abe ama-ion ashajwa ngokukhululeka kwezinye izinyibilikisi (isb, amanzi, utshwala).Isibonelo, i-sodium chloride (NaCl), usawoti osetshenziswa nsuku zonke, incibilika emanzini futhi i-ionize, ikhiqize ama-ion e-sodium ashajwa mahhala (Na+) kanye nama-ion e-chloride ane-negative (Cl).Okusho ukuthi, uma i-HPMC ifakwa emanzini, ayihlukanisi kuma-ion ashajiwe, kodwa ikhona ngendlela yamangqamuzana.
