I-Putty powder iwuhlobo lwezinto zokwakha zokuhlobisa, izingxenye eziyinhloko ziyi-talcum powder neglue. Ungqimba olumhlophe ebusweni begumbi elingenalutho elisanda kuthengwa yi-putty. Ngokuvamile ubumhlophe be-putty bungaphezu kuka-90 ° futhi ubucwebe bungaphezu kuka-330 °.
I-Putty iwuhlobo lwezinto eziyisisekelo ezisetshenziselwa ukulungisa udonga, okubeka isisekelo esihle sesinyathelo esilandelayo sokuhlobisa (ukudweba nephepha lodonga). I-Putty ihlukaniswe yaba izinhlobo ezimbili: i-putty yangaphakathi yodonga kanye ne-putty odongeni lwangaphandle. I-wall putty yangaphandle ingamelana nomoya nelanga, ngakho-ke ine-gelation enhle, amandla aphezulu kanye nenkomba ephansi yemvelo. Inkomba ebanzi ye-putty odongeni lwangaphakathi inhle, futhi ihlanzekile futhi ihambisana nemvelo. Ngakho-ke, udonga lwangaphakathi alulona ukusetshenziswa kwangaphandle futhi udonga lwangaphandle alulona ukusetshenziswa kwangaphakathi. Ama-putty ngokuvamile asekelwe ku-gypsum noma kusimende, ngakho izindawo ezimaholoholo kulula ukuzibopha ziqine. Kodwa-ke, ngesikhathi sokwakhiwa, kusadingeka ukuxubha ungqimba lwe-agent ye-interface esisekelweni ukuze uvale isisekelo futhi uthuthukise ukunamathela odongeni, ukuze i-putty ihlanganiswe kangcono nesisekelo.
Abasebenzisi abaningi be-putty powder kufanele bavume ukuthi ukuchithwa kwe-putty powder kuyinkinga enkulu kakhulu. Kuzokwenza ukuthi upende lwe-latex liwe, kanye nokuqhuma nokuqhekeka kwesendlalelo se-putty, okuzobangela ukuqhekeka ekugcineni kwepende ye-latex.
I-De-powdering kanye nokumhlophe kwe-putty powder okwamanje yizinkinga ezivame kakhulu ngemva kokwakhiwa kwe-putty. Ukuze siqonde izizathu ze-putty powder de-powdering, kufanele siqale siqonde izingxenye eziyisisekelo zezinto ezibonakalayo kanye nezimiso zokuphulukisa ze-putty powder, bese sihlanganisa ubuso bodonga ngesikhathi sokwakhiwa kwe-putty Ukoma, ukumuncwa kwamanzi, izinga lokushisa, ukoma kwesimo sezulu, njll.
Izizathu ezi-8 eziyinhloko zokuwa kwe-putty powder.
isizathu esisodwa
Amandla okubopha i-putty akwanele ukubangela ukususwa kwe-powder, futhi umenzi wehlisa izindleko ngokungaboni. Amandla okubopha we-rubber powder ampofu, futhi inani lokwengeza lincane, ikakhulukazi i-putty yangaphakathi yodonga. Futhi izinga leglue lihlobene kakhulu nenani elingeziwe.
Isizathu sesibili
Ifomula yokuklama engenangqondo, ukukhethwa kwezinto ezibonakalayo kanye nezinkinga zesakhiwo kubaluleke kakhulu kufomula ye-putty. Isibonelo, i-hydroxypropyl methylcellulose (HPMC) isetshenziswa njenge-putty engangeni manzi odongeni lwangaphakathi. Nakuba i-HPMC ibiza kakhulu, ayisebenzi kuma-fillers afana ne-double fly powder, i-talcum powder, i-wollastonite powder, njll. Uma kuphela i-HPMC isetshenziswa, izobangela i-delamination. Kodwa-ke, i-CMC ne-CMS ngamanani aphansi ayisusi i-powder, kodwa i-CMC ne-CMS ayikwazi ukusetshenziswa njenge-putty engenamanzi, futhi ayikwazi ukusetshenziswa njenge-putty yangaphandle yodonga, ngoba i-CMC ne-CMS isabela nge-gray calcium powder kanye nosimende omhlophe, okuzobangela delamination. Kukhona futhi i-polyacrylamides engezwe ku-lime calcium powder kanye nosimende omhlophe njengezimbotshana ezingangeni manzi, okuzophinde kubangele ukusabela kwamakhemikhali kubangele ukukhishwa kwempushana.
Isizathu Sesithathu
Ukuxuba okungalingani kuyisizathu esiyinhloko sokukhishwa kwempuphu ye-putty ezindongeni zangaphakathi nangaphandle. Abanye abakhiqizi ezweni bakhiqiza i-putty powder ngemishini elula nehlukahlukene. Akuzona imishini ekhethekile yokuxuba, futhi ukuxuba okungalingani kubangela ukukhishwa kwempuphu ye-putty.
Isizathu sesine
Iphutha enqubweni yokukhiqiza libangela ukuthi i-putty ibe yimpuphu. Uma i-mixer ingenawo umsebenzi wokuhlanza futhi kunezinsalela ezengeziwe, i-CMC ku-putty evamile izosabela nge-ash calcium powder ku-putty engangeni manzi. I-CMC ne-CMS ku-putty odongeni lwangaphakathi kanye nodonga lwangaphandle Usimende omhlophe we-putty usabela ukuze kukhishwe i-powdering. Imishini ekhethekile yezinkampani ezithile ifakwe ichweba lokuhlanza, elingahlanza izinsalela emshinini, hhayi kuphela ukuqinisekisa ikhwalithi ye-putty, kodwa futhi ukusebenzisa umshini owodwa ngezinjongo eziningi, futhi uthenge umshini owodwa ukukhiqiza izinhlobonhlobo ezihlukahlukene. i-putty.
Isizathu Sesihlanu
Umehluko wekhwalithi yama-filler nawo kungenzeka ukuthi ubangele ukubola kwempuphu. Inani elikhulu lama-fillers asetshenziswa ngaphakathi nangaphandle odongeni putty, kodwa okuqukethwe kwe-Ca2CO3 ku-powder ye-calcium esindayo kanye ne-talc powder ezindaweni ezihlukahlukene kuhlukile, futhi umehluko ku-pH uzophinde ubangele ukubola kwe-putty, njengalezo. eChongqing naseChengdu. Impushana yerabha efanayo isetshenziselwa i-putty powder yodonga lwangaphakathi, kodwa i-talcum powder ne-calcium powder enzima zihlukile. E-Chongqing, ayisusi impushana, kodwa e-Chengdu, ayisusi impushana.
isizathu sesithupha
Isizathu sesimo sezulu siyisizathu sokukhishwa kwempuphu ye-putty ezindongeni zangaphakathi nangaphandle. Isibonelo, i-putty ezindongeni zangaphakathi nangaphandle inesimo sezulu esomile kanye nomoya omuhle kwezinye izindawo ezomile enyakatho. Kukhona isimo sezulu esinemvula, umswakama wesikhathi eside, impahla yokwenza ifilimu ye-putty ayilungile, futhi izophinde ilahlekelwe i-powder, ngakho-ke ezinye izindawo zifanelekile i-putty engenamanzi ne-calcium powder.
isizathu sesikhombisa
Izibophezelo ze-inorganic ezifana nempushana ye-calcium empunga nosimende omhlophe zingcolile futhi ziqukethe inani elikhulu lempuphu ephindwe kabili. Okubizwa ngokuthi i-multi-functional grey calcium powder kanye nosimende omhlophe osebenza ngezinto eziningi emakethe angcolile, ngoba kusetshenziswa inani elikhulu lalezi zibophezelo ezingcolile ze-inorganic, futhi i-putty engangeni manzi yezindonga zangaphakathi nangaphandle nakanjani izoba ngaphandle kwempushana. futhi hhayi amanzi.
isizathu sesishiyagalombili
Ehlobo, ukugcinwa kwamanzi kwe-putty ezindongeni zangaphandle akwanele, ikakhulukazi ezindaweni ezinezinga lokushisa eliphezulu kanye nomoya omncane njengeminyango namafasitela aphakeme kakhulu. Uma isikhathi sokuqala sokusetha se-ash calcium powder kanye ne-cement singanele, sizolahlekelwa amanzi, futhi uma singagcinwa kahle, sizophinde sibe yimpuphu ejulile.
