Hydroxypropyl methyl cellulose(hpmc)waxaa guud ahaan loo isticmaalaa budada putty oo leh mawjadaha 100000, halka hoobiye uu leeyahay shuruudo aad u sarreeya oo loogu talagalay viscosity oo waa in lagu doortaa 150000 viscosity si loo isticmaalo si wanaagsan. Shaqada ugu muhiimsan eehydroxypropyl methyl cellulosewaa in la ilaaliyo biyaha, oo ay ku xigto dhumucdi. Sidaa darteed, budada putty, ilaa inta biyaha lagu hayo la gaaro iyo viscosity hoose, sidoo kale waa suurtagal. Guud ahaan marka loo hadlo, viscosity-ku sarreeyo, ayaa sii wanagsan sii haynta biyaha. Si kastaba ha ahaatee, marka viscosity ka badan yahay 100000, saamaynta viscosity on haynta biyaha ma aha mid muhiim ah.

Darajada Qalabka Dhismaha JufuHydroxypropyl Methyl CelluloseWaxaa lagu gartaa Viscosity, guud ahaan waxa loo qaybiyaa noocyada soo socda:

1. Viscosity hoose: 400 viscosity cellulose, inta badan loo isticmaalo hoobiye is-mida. Viscosity hoose, socodka wanaagsan, iyo ka dib marka lagu daro, waxay xakameyn doontaa ilaalinta biyaha dusha sare. Dhiigbaxa ma cadda, dhimashadu waa yar tahay, dildilaacana waa la yareeyaa. Waxa kale oo ay iska caabin kartaa suuxdin, kor u qaadida socodka iyo bamgareynta.
2. Dhexdhexaad ilaa hoose: 20000 ilaa 50000 viscosity cellulose, inta badan loo isticmaalo alaabta gypsum iyo buuxinta wadajirka ah. Mawduuc hoose, haynta biyaha wanaagsan, karti-shaqayn wanaagsan, iyo biyo-kordhin hoose
3. Viscosity dhexdhexaad ah: 75000-100000 viscosity cellulose, inta badan loo isticmaalo gudaha iyo dibadda derbiga. Viscosity dhexdhexaad ah, haynta biyaha wanaagsan, iyo daahyada dhismaha oo wanaagsan.
4. Viscosity High: 150000 ilaa 200000 yuan, inta badan loo isticmaalo polystyrene insulation insulation maaddooyinka budada ah, hoobiye dahaarka vitrified micro leed leh viscosity sare iyo haynta biyaha. Hoobiyeyaasha ma fududa in la soo tuuro oo la laadlaadsado, hagaajinta dhismaha.
Guud ahaan marka loo hadlo, viscosity-ku sarreeyo, ayaa sii wanagsan sii haynta biyaha. Sidaa darteed, macaamiil badani waxay doortaan inay isticmaalaan cellulose viscosity dhexdhexaad ah (75000-100000) halkii ay ka ahaan lahaayeen cellulose dhexdhexaad ah oo hooseeya (20000-50000) si loo yareeyo qadarka isku-darka iyo kharashka xakamaynta.
viscosity eeHPMCwaxay u dhigantaa si ka duwan heerkulka, si kale haddii loo dhigo, viscosity wuxuu kordhiyaa hoos u dhaca heerkulka. Viscosity ee badeecadu waxay ka dhigan tahay in 2% xalkeedu uu ku jiro heerkul ah 20 darajo Celsius, natiijaduna waa sax.
Codsiyada gaarka ah, fiiro gaar ah waa in la siiyaa meelaha leh farqiga heerkulka weyn ee u dhexeeya xagaaga iyo jiilaalka, waxaana si xoog leh loogu talinayaa in la isticmaalo viscosity hoose xilliga jiilaalka. Haddii kale, haddii viscosity hooseeyo, viscosity of cellulose waa kordhin doonaa iyo xagashada noqon doonaa culus.
