Abakhiqizi be-HPMC - umphumela we-viscosities ahlukene ye-cellulose afers ku-putty powder

Yethula:

I-Cellulose Afers isetshenziswa kabanzi embonini yezokwakha ngenxa yokugcinwa kwawo kwamanzi okuhle, ukuqina kanye nokubopha izakhiwo. Bathuthukisa ukugeleza nokukhononda kwezinto zokwenziwa kokhonkolo futhi bathuthukise izakhiwo zemishini zomkhiqizo wokugcina. Amabhoti ajwayele ukusetshenziswa embonini yezokwakha ukugcwalisa imifantu, izimbobo nokunye ukungapheleli ezindongeni nophahla. Ukusetshenziswa kwe-cellulose izithathekisa kumaPunTY Powders kungathuthukisa ukuwenza, ukusetha isikhathi nekhwalithi ephelele yomkhiqizo. Le ndatshana izodingida umphumela we-viscosities ahlukene ye-cellulose ether ku-putty powder.

Izinhlobo ze-cellulose afes:

Kunezinhlobo ezahlukene ze-cellulose 'tiler kufaka phakathi i-methylcellulose (MC), i-hpdroxypropylethcelellulose (HPMC), ethylcellulose (ec) kanye ne-carboxymethylcelellellellellellellellellellellellellellellellellellellellellellellellulose (CMC). I-HPMC iyi-ether ye-cellulose ethandwayo embonini yezokwakha ngenxa yokugcinwa kwayo okuhle kakhulu kwamanzi, ukuqina nokunamathela. I-HPMC iza ngezinto ezihlukile, kusuka kokuphansi kuya phezulu.

Umphumela we-cellulose ether ku-putty powder:

I-PuTTY powder isetshenziselwa ukugcwalisa imifantu, izimbobo nokunye ukungapheleli ezindongeni nophahla. Ukusetshenziswa kwe-cellulose izithathekisa kumaPunDty Powders kungathuthukisa ukuwenza nokusetha isikhathi somkhiqizo. I-Cellulose Ether ingathuthukisa futhi ukusebenziseka nokunamathelisa kwe-putty powder. Lokhu okulandelayo kungumphumela we-viscosities ahlukile we-cellulose ether ku-Putty Powder:

1. Insizwa ephansi i-HPMC:

I-viscosity ephansi i-HPMC ingathuthukisa uketshezi nokusebenza kwe-putty powder. Kubuye kuthuthukise isikhathi sokusetha komkhiqizo. I-Low-Viscosity HPMC inokushisa okuphansi kwe-gelation, okungavimba i-putty powder kusuka ekuqiniseni ngokushesha okukhulu. Kungathuthukisa futhi ukunamathela kanye nokubumbana komkhiqizo. I-viscosity ephansi i-HPMC ilungele impuphu kaPutty edinga ukusebenziseka okuhle nokubusheleleka.

2. I-Medium Viscosity HPMC:

I-Medium Viscosity HPMC ingathuthukisa izakhiwo ze-Thixotropic ze-Putty Powder. Kungathuthukisa futhi ukugcinwa kwamanzi kanye nokusebenza kwebhondi komkhiqizo. I-Medium-Viscutity HPMC ingathuthukisa izakhiwo zemishini zomkhiqizo, njengamandla nokuqina. Ilungele i-putty powder edinga ukugcinwa okuhle kwamanzi kanye nokubumbana.

I-3.

I-Vissevotity ephezulu i-HPMC ingathuthukisa ukusebenza kokuqina nokulwa ne-SAG kaPutty Powder. Kungathuthukisa futhi ukugcinwa kwamanzi kanye nokusebenza kwebhondi komkhiqizo. I-Vissevotity ephezulu i-HPMC ingathuthukisa izakhiwo zemishini zomkhiqizo, njengamandla nokuqina. Ilungele i-putty powder edinga ukuqina okuphezulu nokusebenza kwe-anti-sag.

Ekuphetheni:

I-Cellulose Afers isetshenziswa kabanzi embonini yezokwakha ngenxa yokugcinwa kwawo kwamanzi okuhle, ukuqina kanye nokubopha izakhiwo. I-HPMC isiphenduke i-cellulose ether ethandwayo embonini yezokwakha ngenxa yezakhiwo zayo ezinhle kakhulu. I-HPMC iza ngezinto ezihlukile, kusuka kokuphansi kuya phezulu. Ukusetshenziswa kwezithako ze-cellulose ezinama-visosities ahlukene kungathuthukisa ukusebenza, ukusetha isikhathi, ukusebenza kwe-Thixotropic, ukugcinwa kwamanzi, ukusebenza okubophayo kanye nezakhiwo zemishini ze-putty powder. Ukusetshenziswa kwezithathela ze-cellulose kungathuthukisa ikhwalithi nokusebenza kwama-powders ama-putty, kubenze balungele izinhlelo ezahlukahlukene embonini yezokwakha.
