Waa maxay viscosity ugu habboon ee hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose waxaa guud ahaan loo isticmaalaa budada suufka leh oo leh mawjadaha 100,000, halka hoobiye uu leeyahay shuruudo aad u sarreeya, sidaas darteed waa in lagu isticmaalo maqaar 150,000 ah. Shaqada ugu muhiimsan ee hydroxypropyl methylcellulose waa haynta biyaha, oo ay ku xigto dhumucdi. Sidaa darteed, budada putty, ilaa inta biyaha lagu hayo la gaaro, viscosity ayaa hooseeya. Guud ahaan, marka uu ba'an yahay mawduucyada, ayaa sii fiicnaanaya haynta biyaha, laakiin marka muuqashadu ka badato 100,000, majiishu wax yar ayay ku yeelanaysaa haynta biyaha.

Marka loo eego viscosity, hydroxypropyl methylcellulose guud ahaan waxaa loo qaybiyaa noocyada soo socda:

1. Viscosity hoose: 400 viscosity cellulose, inta badan loo isticmaalo hoobiyeyaasha is-milliminta.
Waxay leedahay viscosity hoose iyo dareere wanaagsan. Ka dib marka lagu daro, waxay xakameyn doontaa haynta biyaha ee dusha sare, dhiig-baxa maaha mid cad, yareyntu waa yar tahay, dildilaaca waa la yareeyaa, sidoo kale waxay ka hortagi kartaa suuxdinta waxayna kor u qaadi kartaa dareeraha iyo bamka.

2. Dhexdhexaad iyo viscosity hoose: 20,000-50,000 viscosity cellulose, inta badan loo isticmaalo alaabta gypsum iyo wakiilada caulking.
Mawduuc hoose, haynta biyaha sare, karti-shaqayn wanaagsan, biyo yar oo lagu daray

3. Viscosity dhexdhexaad ah: 75,000-100,000 viscosity cellulose, inta badan loo isticmaalo gudaha iyo dibadda derbiga.
Viscosity dhexdhexaad ah, haynta biyaha oo wanaagsan, dhismo wanaagsan iyo karti

4. Viscosity sare: 150,000-200,000, inta badan loo isticmaalo polystyrene insulation insulation hoobiye caag budada ah, vitrified microbead insulation hoobiye
Iyada oo viscosity sare iyo haynta biyaha sare, hoobiye ma fududa in la daadiyo dambaska iyo sag, taas oo hagaajinaysa dhismaha.

Guud ahaan, marka la eego heerka sare ee viscosity, ayaa sii wanagsanaanta biyaha, sidaas darteed macaamiil badan ayaa dooran doona inay isticmaalaan cellulose dhexdhexaad ah (75,000-100,000) halkii ay ka ahaan lahaayeen cellulose dhexdhexaad ah (20,000-50,000) si loo yareeyo qadarka lagu daray, ka dibna kharashka xakamaynta
