Chifukwa chomwe hydroxypropyl methylcellulose imasungunuka kwambiri mu putty powder

Chifukwa chiyani hydroxypropyl methylcellulose imasungunuka kwambiri mu putty powder?

Pamene ufa wa putty umapangidwa ndikugwiritsidwa ntchito, mavuto osiyanasiyana amayamba.Pambuyo pake ufa wa putty usakanizidwa ndi madzi ndikugwedezeka ndi kubowola kwamagetsi, putty idzakhala yowonda kwambiri pamene ikugwedezeka, ndipo chodabwitsa cha kulekanitsa madzi chidzakhala chachikulu.Choyambitsa cha vutoli ndi putty.Hydroxypropyl methylcellulose yowonjezeredwa ku ufa.

1. Kukhuthala kwa hydroxypropyl methylcellulose sikoyenera, mamasukidwe akayendedwe ndi otsika kwambiri, ndipo kuyimitsidwa sikukwanira.Panthawiyi, chodabwitsa cha kulekanitsa madzi chidzakhala chachikulu, ndipo zotsatira za kuyimitsidwa kwa yunifolomu sizingawonekere.

2. Hydroxypropyl methylcellulose wothandizira madzi amawonjezeredwa ku ufa wa putty, womwe uli ndi zotsatira zabwino kwambiri zosungira madzi.Putty ikasungunuka m'madzi, imatseka madzi ambiri.Pa nthawi imeneyi, madzi ambiri flocculated m'madzi.Chotupacho, ndi kusonkhezera, madzi ambiri amalekanitsidwa, kotero pali vuto kuti mukamasonkhezera kwambiri, limakhala lochepa thupi;ili ndi vuto lofala, ndipo anthu ambiri akumanapo ndi vuto lotere.Kuchuluka kwa cellulose kuwonjezeredwa kapena chinyezi chowonjezera kumatha kuchepetsedwa moyenera.

3. Hydroxypropyl methylcellulose ili ndi ubale wina ndi kapangidwe kake.Lili ndi thixotropy, kotero kuti ❖ kuyanika konse kumakhala ndi thixotropy wina pambuyo powonjezera mapadi, kotero pamene putty imagwedezeka mofulumira, mawonekedwe ake onse Obalalika, amawonekera mowonjezereka, koma akaima, amachira pang'onopang'ono.
