Njengamanje, ikhwalithi ye-hydroxpelloselloselproxypropyllose yasekhaya iyahluka kakhulu, futhi intengo iyahluka kakhulu, okwenza kube nzima kumakhasimende ukwenza isinqumo esifanele. I-HPMC eguquliwe yenkampani yakwamanye amazwe efanayo ingumphumela weminyaka eminingi yocwaningo. Ukungezwa kwezinto ezilandelwayo kungathuthukisa ukusebenza kokwakha futhi kuthuthukise ukusebenza. Vele, kuzothinta ezinye izakhiwo, kepha ngokuvamile zikhuluma kusebenza kahle; Ukuphela kwenhloso yokwengeza ezinye izithako ukunciphisa izindleko, okuholele ekugcinweni kwamanzi okuncishisiwe, ukubumbana nezinye izakhiwo zomkhiqizo, okuholela ezinkingeni eziningi zekhwalithi yokwakha.
Kunomehluko olandelayo phakathi kwe-HPMC emsulwa ne-HPMC ephiwe:
1. I-HPMC ehlanzekile i-fluffy ebonakalayo futhi inobunzima obuphansi obuphansi, kusukela ku-0.3-0.4g / ml; I-HPMC ephindwe nge-FPMC inobunzima obungcono futhi izizwe isindayo, okusobala okuhlukile kumkhiqizo wangempela ngokubukeka.
2 Isixazululo se-HPMC samanzi se-HPMC sinamafu, kanti izinga lokugcina amanzi linzima ukufinyelela kuma-80%.
3. I-HPMC ehlanzekile akufanele imonge i-ammonia, isitashi notshwala; I-HPMC ye-Aleelped ivame ukunuka zonke izinhlobo zokuhogela, noma ngabe ayinambitha, kuzozizwa zisinda.
4. I-puree hpmc powder i-fibrous ngaphansi kwesibonakhulu noma ingilazi ekhulisa; I-HPMC ye-Aleelped ingabhekwa njengezinsimbi ze-granular noma amakristalu ngaphansi kwesibonakhulu noma ingilazi ekhulisa.
Ukuphakama okungenakunqotshwa kwama-200,000?
Ochwepheshe abaningi basekhaya kanye nezazi zishicilele amaphepha akholelwa ukuthi ukukhiqizwa kwe-HPMC kukhawulelwe ukuphepha kwemishini yasekhaya nokubekwa uphawu, amabhizinisi aphansi kanye nokukhiqizwa kwengcindezi ephansi, namabhizinisi ajwayelekile awakwazi ukukhiqiza imikhiqizo enokubonakala kwabantu abangaphezu kuka-200,000. Ehlobo, akunakwenzeka ngisho ukukhiqiza imikhiqizo enokubonakala okungaphezulu kwama-80,000. Bakholelwa ukuthi imikhiqizo ebizwa ngokuthi yi-200,000 kumele ibe yimikhiqizo engelona iqiniso.
Izimpikiswano zesazi azinangqondo. Ngokwesimo sangaphambilini sokukhiqiza ekhaya, iziphetho ezingenhla zingadonswa ngempela.
Isihluthulelo sokwandisa i-viscosity ye-HPMC ukubekwa uphawu okuphezulu kokuphendula kwe-reactor kanye nokucindezela okuphezulu kanye nezinto zokwakha ezisezingeni eliphakeme. Ukuqina komoya okuphezulu kuvimbela ukonakaliswa kwe-cellulose ngomoya-mpilo, kanye nesimo sokuphendula okufunwa kakhulu kuthuthukisa ukungena kwe-ejenti yokusheshisa kanye nokuqinisekisa ukufana komkhiqizo kanye nokuqinisekisa ukufana komkhiqizo.
Inkomba eyisisekelo ye-200000CPS HYDROXYPROPYL Methylcellulose:
I-2% isisombululo esinamanzi esingu-200000cps
Ukuhlanzeka komkhiqizo ≥98%
Okuqukethwe kwe-methoxy 19-24%
Okuqukethwe kwe-Hydroxypropoxy: 4-12%
200000cps hydroxyproppropyl methylcellulose izici:
1. Ukugcinwa kwamanzi okuhle kakhulu kanye nokuqina kwezindawo ukuqinisekisa i-hydration ephelele ye-slurry.
2. Amandla aphezulu okubopha kanye nomphumela obalulekile wokufaka umoya, uvimbela ngempumelelo i-shrinkage kanye nokuqhekeka.
I-3. Ibambezela ukukhishwa kokushisa kuka-Cement Hydration, ukubambezeleka isikhathi sokusetha, futhi alawule isikhathi esisebenzayo sodaka kasimende.
4. Thuthukisa ukuguquguquka kwamanzi kodaka olunempompo, thuthukisa i-bheology, futhi uvikele ukuhlukaniswa nokopha.

Ngenxa yokubhekwa kwemakethe ye-lax, umncintiswano embonini kamonakalo uya ngokuya ukhula. Ukuze ubheke emakethe, abanye abathengisi baxube inani elikhulu lezinto ezibiza kakhulu ukukhiqiza i-ether eshibhile ye-cellulose ether. Lapha, umhleli uphoqelekile ukukhumbuza amakhasimende ukuthi angaphishekele izintengo eziphansi, ukuze angakhohliswa ukuthi akhohliswe, aholele ezingozini zobunjiniyela, futhi ekugcineni ukulahleka kudlula izinzuzo.
Izindlela ezijwayelekile zokuphinga nezindlela zokuhlonza:
.
Indlela yokuhlonza: Ngenxa yezimpawu zezingadi, lolu hlobo lwe-cellulose ether isixazululo luvame ukuba nomcucu ojwayelekile, kepha i-ether enhle ye-cellulose ngeke ibonakale ngentambo ye-stromenon ngemuva kokuchithwa, isixazululo sifana nejelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yijelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly, okubizwa ngokuthi yi-jelly.
(2) Faka isitashi ku-cellulose ether. Isitashi ngokuvamile singenakufakwa emanzini, futhi isixazululo sivame ukudluliswa okulula kokukhanya.
Indlela yokuhlonza: Donsela i-Cellulose Ether Isixazululo nge-Iodine, uma umbala uphenduka uluhlaza okwesibhakabhaka, kungacatshangelwa ukuthi kufakiwe isitashi.
(3) Faka i-polyvinyl alcohol powder. Njengoba sonke sazi, intengo yemakethe ye-polyvinyl alcohol powder enjenge-2488 no-1788 ivame ukwedlula leyo ye-cellulose ether, kanye ne-polyvinyl alcohol powder kunganciphisa izindleko ze-cellulose ether.
Indlela yokuhlonza: lolu hlobo lwe-cellulose ether luvame ukufana nobuntu. Incibilikisa ngokushesha ngamanzi, khetha ikhambi ngenduku yengilazi, kuzoba khona into ecashile ngokwengeziwe.
Isifinyezo: Ngenxa yesakhiwo sayo namaqembu akhethekile, ukugcinwa kwamanzi kwe-cellulose ether akunakuphikwa ezinye izinto. Akunandaba noma uhlobo luhlobo luni lwe-filler oluxutshwe, inqobo nje uma luhlanganiswa ngenani elikhulu, ukugcinwa kwalo kwamanzi kuzoncishiswa kakhulu. Inani le-HPMC elinokubonakala okujwayelekile kwe-10w ku-motar ojwayelekile ngu-0,15 ~ 0.2 ‰, kanye nenani lokugcinwa kwamanzi lingu-88%. Ukopha kubi kakhulu. Ngakho-ke, inani lokugcinwa kwamanzi liyinkomba ebalulekile yokukala ikhwalithi ye-HPMC, noma ngabe yinhle noma imbi, inqobo nje uma ingezwe ku-datar, kuzocaciswa shazi.
