Hydroxypropyl methylcelluloseoo leh viscosity of 100,000 ayaa guud ahaan ku filan budada putty, halka hoobiye uu leeyahay shuruudo aad u sarreeya oo loo baahan yahay viscosity, sidaas darteed 150,000 viscosity waa in la doortaa si loo isticmaalo si fiican. Shaqada ugu muhiimsan eehydroxypropyl methylcellulosewaa xajinta biyaha, oo ay ku xigto dhumucdi. Sidaa darteed, budada putty, ilaa inta biyaha lagu hayo la gaaro, viscosity hoose ayaa sidoo kale la aqbali karaa. Guud ahaan, mar kasta oo uu viscosity-ku sarreeyo, ayaa sii wanagsanaanta sii-haysashada biyaha, laakiin marka muuqa-beelka uu ka bato 100,000, saamaynta maangalku ku leeyahay haynta biyaha maaha mid muhiim ah.
Hydroxypropyl methylcelluloseguud ahaan waxa loo qaybiyaa qaybaha soo socda iyadoo loo eegayo viscosity:
1. Viscosity hoose: 400 viscosity cellulose, inta badan loo isticmaalo hoobiyeyaasha is-milliminta.
Viscosity hoose, dheecaan wanaagsan, ka dib marka lagu daro waxay xakameyn doontaa haynta biyaha dusha sare, jeexjeexa biyuhu maaha mid cad, hoos u dhacu waa yar yahay, dildilaaca waa la dhimay, sidoo kale waxay iska caabin kartaa qulqulka, kor u qaadida dareeraha iyo bamka.
2. Mawjad hoose oo dhexdhexaad ah: 20,000-50,000 viscosity cellulose, inta badan loo isticmaalo alaabta gypsum-ka iyo wakiilada caulking.
Maqnaanshaha hoose, xajinta biyaha, waxqabadka dhismaha ee wanaagsan, kordhinta biyaha oo yar.
3. Viscosity dhexdhexaad ah: 75,000-100,000 viscosity cellulose, inta badan loo isticmaalo gudaha iyo dibadda derbiga.
Viscosity dhexdhexaad ah, haynta biyaha wanaagsan, dhismo wanaagsan iyo guryaha laadlaadsan
4. viscosity sare: 150,000-200,000, inta badan loo isticmaalo polystyrene insulation insulation hoobiye xabagta budada ah iyo vitrified dhogorta insulation micro-kuul. Viscosity sare, haynta biyaha sare, hoobiye ma fududa in ay dhacaan, socodka, hagaajinta dhismaha.
Guud ahaan marka loo hadlo, viscosity-ku sarreeyo, ayaa sii wanagsan sii haynta biyaha. Sidaa darteed, macaamiil badan ayaa dooran doona inay isticmaalaan cellulose dhexdhexaad ah (75,000-100,000) halkii ay ka ahaan lahaayeen cellulose dhexdhexaad ah oo hooseeya (20,000-50,000) si loo yareeyo qaddarka lagu daray oo sidaas darteed loo xakameeyo kharashyada.
Hydroxypropyl methylcellulose (HPMC)waa polymer semisynthetic ah oo caadi ahaan loo isticmaalo warshado kala duwan, oo ay ku jiraan dhismaha, daawooyinka, iyo wax soo saarka cuntada. Viscosity ee HPMC waa hanti muhiim ah oo go'aamisa waxqabadkeeda codsiyada kala duwan.
Viscosity ee HPMC waxaa saameeya arrimo ay ka mid yihiin heerka beddelka (DS), miisaanka kelli, iyo xoogga saaridda xalka HPMC. Guud ahaan, marka heerka beddelka iyo miisaanka kelli ee HPMC uu kordho, sidaas oo kale maw-jiidkiisu wuu kordhaa.
HPMC waxa lagu heli karaa noocyo kala duwan oo darajooyin viscosity ah, sida caadiga ah lagu qiyaaso marka la eego "miisaanka kellika ah" ama "ka kooban methoxyl." Viscosity ee HPMC waxaa lagu beddeli karaa iyadoo la dooranayo fasalka ku habboon ama iyadoo la hagaajinayo diiradda HPMC xal.
Codsiyada dhismaha, HPMC oo leh viscosity sare ayaa badanaa loo isticmaalaa si loo hagaajiyo kartida iyo haynta biyaha ee alaabta sibidhka ku salaysan. Daawooyinka, viscosity waa arrin muhiim ah oo lagu xakameynayo heerka sii deynta maaddooyinka firfircoon ee daawooyinka daroogada.
Sidaa darteed, fahamka viscosity ee hydroxypropyl methylcellulose ayaa muhiim u ah xulashada darajada saxda ah ee codsiyada gaarka ah iyo hubinta sifooyinka waxqabadka la doonayo.
