Ko te Hydroxypropyl methylcellulose e whakamahia ana i roto i te paura putty me te 100,000 viscosity, i te mea he nui te whakaritenga o te moata, no reira me whakamahi ki te 150,000.Ko te mahi tino nui o te hydroxypropyl methylcellulose ko te pupuri i te wai, ka whai muri i te whakapakeke.Na reira, i roto i te paura putty, i te mea ka tutuki te pupuri wai, ka iti ake te viscosity.I te nuinga o te korero, ko te nui ake o te viscosity, ko te pai ake o te pupuri i te wai, engari ka neke ake te viscosity ki te 100,000, he iti noa te paanga o te viscosity ki te pupuri wai.
E ai ki te viscosity, ka wehewehea te hydroxypropyl methylcellulose ki nga momo e whai ake nei:
1. Iti pokey: 400 pokey cellulose, te nuinga whakamahia mō te kumete whakaōrite-whaiaro.
He iti te pokey me te rere pai.I muri i te taapiri, ka whakahaerehia e ia te pupuri i te wai o te mata, kaore i te kitea te toto, he iti te whakaheke, ka heke te pakaru, ka taea hoki te aukati i te parataiao me te whakarei ake i te rere me te papu.
2. Waenga me te iti viscosity: 20,000-50,000 viscosity cellulose, te nuinga whakamahia i roto i ngā hua gypsum me āpiha caulking.
He iti te pokey, he nui te pupuri wai, he pai te mahi, he iti te wai taapiri,
3. Pokey Waenga: 75,000-100,000 viscosity cellulose, te nuinga whakamahia mo te putty taiepa o roto me waho.
Pokey āhua, pai te pupuri wai, pai hanga me te drapability
4. Te pokey teitei: 150,000-200,000, te nuinga whakamahia mo te matūriki polystyrene matūriki matūriki moata rapa rapa paura, vitrified microbead moata rara
Ma te nui o te pokey me te nui o te pupuri i te wai, kaore i te ngawari te whakaheke i te pungarehu me te pakaru, ka pai ake te hanga.
I te nuinga o te korero, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai, na te maha o nga kaihoko ka whiriwhiri ki te whakamahi i te cellulose reo-viscosity (75,000-100,000) hei utu mo te cellulose viscosity medium-iti (20,000-50,000) hei whakaiti i te moni taapiri, katahi ka utu whakahaere
