Hydroxypropyl methylcelluloseine viscosity ye100,000 inowanzokwana mu putty powder, nepo dhaka rine chidimbu chepamusoro chinodiwa che viscosity, saka viscosity ye150,000 inofanira kusarudzwa kuti ishandiswe zviri nani. Basa rakakosha rehydroxypropyl methylcellulosendiko kuchengetwa kwemvura, kuchiteverwa nekukora. Nokudaro, muputty powder, chero bedzi kuchengetwa kwemvura kunowanikwa, kuderera kwepasi kunogamuchirwa zvakare. Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura, asi kana viscosity inopfuura 100,000, mhedzisiro yeviscosity pakuchengetedza mvura haina kukosha.
Hydroxypropyl methylcelluloseinowanzo kupatsanurwa muzvikamu zvinotevera maererano ne viscosity:
1. Low viscosity: 400 viscosity cellulose, inonyanya kushandiswa kune self-leveling mortar.
Low viscosity, yakanaka fluidity, mushure mekuwedzera iyo ichadzora kuchengetwa kwemvura pamusoro, mvura inoyerera haisi pachena, shrinkage idiki, kuputika kunoderedzwa, uye inogonawo kuramba sedimentation, kuwedzera fluidity uye pumpability.
2. Medium-low viscosity: 20,000-50,000 viscosity cellulose, inonyanya kushandiswa kune zvigadzirwa zvegypsum uye caulking agents.
Low viscosity, kuchengetwa kwemvura, kuita kwakanaka kwekuvaka, kushomeka kwekuwedzera kwemvura.
3. Medium viscosity: 75,000-100,000 viscosity cellulose, inonyanya kushandiswa mukati nekunze kwemadziro putty.
Moderate viscosity, yakanaka kuchengetedza mvura, kuvaka kwakanaka uye kurembera zvivakwa
4. High viscosity: 150,000-200,000, inonyanya kushandiswa polystyrene particle insulation mortar glue powder uye vitrified micro-bead insulation mortar. High viscosity, kuchengetwa kwemvura yakakwirira, dhaka haisi nyore kudonha, kuyerera, kunatsiridza kuvaka.
Kazhinji kutaura, iyo yakakwirira viscosity, zviri nani kuchengetedza mvura. Nokudaro, vatengi vakawanda vachasarudza kushandisa medium-viscosity cellulose (75,000-100,000) panzvimbo yepakati-yakaderera viscosity cellulose (20,000-50,000) kuderedza mari yakawedzerwa uye nokudaro kudzora mari.
Hydroxypropyl methylcellulose (HPMC)is a semisynthetic polymer iyo inowanzoshandiswa mumaindasitiri akasiyana siyana, kusanganisira kuvaka, mishonga, uye kugadzira chikafu. Iyo viscosity yeHPMC chinhu chakakosha chinotarisa kuita kwayo mumashandisirwo akasiyana.
Iyo viscosity yeHPMC inopesvedzerwa nezvinhu zvakaita sedhigirii rekutsiva (DS), uremu hwemamorekuru, uye kusungwa kweiyo HPMC mhinduro. Kazhinji, sezvo dhigirii rekutsiva uye huremu hwemamorekuru hweHPMC hunowedzera, ndizvo zvinoitawo viscosity yayo.
HPMC inowanikwa mumhando dzakasiyana-siyana dze viscosity mamakisi, anowanzo kuyerwa maererano ne "molecular weight" kana "methoxyl content." Iyo viscosity yeHPMC inogona kugadziridzwa nekusarudza giredhi rakakodzera kana nekugadzirisa kusungwa kweiyo HPMC mhinduro.
Mukuvaka maapplication, HPMC ine yakakwira viscosity inowanzo shandiswa kuvandudza kushanda uye kuchengetwa kwemvura yesimende-yakavakirwa zvinhu. Mumishonga yemishonga, viscosity chinhu chakakosha pakudzora kusunungurwa kwehuwandu hwezvinhu zvinoshanda mukugadzirisa zvinodhaka.
Naizvozvo, kunzwisisa viscosity yehydroxypropyl methylcellulose kwakakosha pakusarudza giredhi rakakodzera remashandisirwo chaiwo uye kuve nechokwadi chemaitiro anodikanwa ekuita.
