Momwe mungadziwire ngati hydroxypropyl methylcellulose yauma

Hydroxypropyl methylcellulose amagwiritsidwa ntchito ngati thickener mu makampani ❖ kuyanika, amene angapangitse ❖ kuyanika owala ndi wosakhwima, osati powdery, ndi kusintha makhalidwe kusanja.Ndiroleni ndikudziwitseni momwe mungayang'anire ngati ufa wa putty wauma.Khoma lauma kwathunthu.Kulankhula mowoneka, mtundu wa makoma onse umakhala wokhazikika komanso woyera, popanda kumva imvi pamene uli wonyowa.Kupaka pang'onopang'ono ndi manja anu, kukhudza kumakhala kosalala, ndipo kudzakhala fumbi pang'ono.

Kapena gwiritsani ntchito sandpaper kuti mupukutire mopepuka, ngati fumbi lalikulu likuwoneka, zikutanthauza kuti ufa wa putty wa wosanjikiza uuma kwathunthu, ndipo ngati pali fumbi lochepa kapena palibe fumbi konse, zikutanthauza kuti ufa wa putty sunaume kwathunthu. .

Nthawi yowuma ya ufa wa putty iyenera kusinthidwa malinga ndi nyengo zosiyanasiyana.M'nyengo yamdima komanso yachinyontho, iyenera kukulitsa nthawi yowumitsa.Muzochitika zachilendo, gawo la ngodya yamkati silophweka kuti liume.Ngati mbali ya ngodya yamkati ndi youma kwathunthu, ndizotheka kunena kuti makoma onse akhala owuma.

Mukamaliza kukongoletsa khoma, nthawi zambiri timafunikira kukwapula pakhoma poyamba, ndipo ntchito yayikulu ya ufa wa putty ndikukweza pamwamba pa khoma, kuti khoma likhale loyera komanso losalala, khoma lingagwiritsidwe ntchito pambuyo pake.Chifukwa chake, ndikofunikira kuwonetsetsa kuti njirazi zikuthetsedwa bwino komanso moyenera.Pakali pano, khalidwe la zoweta hydroxypropyl methylcellulose zimasiyanasiyana kwambiri, ndipo mtengo zimasiyanasiyana ambiri, kupangitsa kukhala kovuta kwa makasitomala kusankha bwino.

Kuphatikizika kwa zinthu zowunikira kumatha kupititsa patsogolo ntchito yomanga ndikuwongolera magwiridwe antchito.Zachidziwikire, zisudzo zina zidzakhudzidwa, koma zonse ndizabwino;pamene zinthu zopangidwa ndi opanga pakhomo zimawonjezera kuchuluka kwa zinthu zina, cholinga chokha ndicho kuchepetsa ndalama , Kusungirako madzi ndi kugwirizanitsa katundu wa mankhwalawa kumachepetsedwa kwambiri, zomwe zimapangitsa kuti pakhale mavuto ambiri a zomangamanga.
