Ndeapi mashandisirwo ehydroxypropyl methylcellulose mukuzvienzanisa?

Hydroxypropyl methylcelluloseinowanzoshandiswa mumaindasitiri akasiyana-siyana. Kunyangwe vanhu vazhinji vasingainzwisise zvakanyanya, inokanganisa maindasitiri akasiyana. Mukugadzira indasitiri yekuvaka, inowanzo shandiswa pakuvaka madziro uye kushongedza stucco, Caulking nedzimwe minda yekuvaka michina, kunyanya mukuvaka kwekushongedza, inowanzoshandiswa kugadzira matairi, marble, uye kumwe kushongedza kwepurasitiki. Iyo ine dhigirii yakakura yekunamatira uye inogona kuderedza huwandu hwesimende inoshandiswa. Inoshandiswa muindastiri yekuputira, inonyanya kushandiswa seyakakora, inogona kuita iyo layer yakanaka uye yakajeka, isiri nyore kubvisa upfu, kuvandudza mashandiro ekuita, nezvimwewo, kunyanya kushandiswa mumunda wekuvaka dhaka rekuzvimisa.

Mubairo wejecha rekuzvimisikidza unonyanya kukosha wakaoma-musanganiswa wedhaka chigadzirwa chine kuenzana uye kuzvigadzirisa. Iyo yekuzvigadzirisa uye yekuzvimisa-leveling kugona kwayo kwakakosha pakuwana isina musono uye yakatsetseka yepasi layer. Kune zvigadzirwa zvakanaka zvekuzvimisa, kutanga Inofanirwa kunge iine mashandiro ekushanda akakodzera, uye kukwanisa kuchengetedza kuita kwayo kwese kwekuita uye kugona kuzvirapa mukati menguva yekuvaka. Nenzira iyi, izvi zvinoda kuti dhaka rive nechokwadi chekugadzikana kwayo uye kufanana mukati meiyi nguva yenguva. Chechipiri, dhaka rinofanira kunge riine rimwe simba, iro rinosanganisira kutakura simba uye simba rekubatanidza kune base base. Aya ndiwo mamiriro ekutanga ekushandiswa kwakajairwa kwezvinhu zvekuzvimisa, uye kuzadzikiswa kwezvinhu izvi zvekuzvimisa zvinoda hydroxypropyl kuwedzera kwemethyl cellulose ether inogona kukora uye kuwedzera viscosity, uye zvakare ine hunhu hwekuchengeta mvura yakanyanya uye kurebesa. nguva yekuvaka.

Iyo yakakwirira iyo viscosity yehydroxypropyl methylcellulose, zviri nani iyo viscosity yeyakagadziridzwa simende-yakavakirwa zvinhu, asi kana viscosity yakanyanya kuwanda, inokanganisa kuyerera uye kushanda kwechinhu. Pamusoro pezvo, iko kukora kwehydroxypropyl methylcellulose inogona zvakare kuwedzera kudiwa kwemvura yesimende-yakavakirwa zvinhu, nekudaro ichiwedzera goho redhaka. Kuzvigadzika dhaka uye kuzvigadzirisa kongiri, izvo zvinoda mvura yakawanda, zvinoda yakaderera viscosity yehydroxypropyl methylcellulose. Iyo yakaderera-viscosity cellulose ether inogona kutamba yakanaka kumisa mhedzisiro, kudzivirira slurry kubva pakugadzirisa, uye zvakare ine basa rekubuda ropa, iro rinogona kuve nechokwadi kuti harizokanganisa kuyerera kweiyo yekuzvimisa-leveling dhaka zvinhu, zviri nyore kuvaka, uye ine kuchengetwa kwemvura yakakwira Hunhu hunogona kuita kuti chimiro chepamusoro mushure mekuenzanisa zviri nani, kuderedza kuderera kwedhaka, uye kudzivirira kupenengura kuputika uye zvichingodaro.

Hydroxypropyl methylcellulose inoshandiswa zvakanyanya mumhando dzakasiyana dzekuvaka. Kana ichishandiswa mudhaka rekuzvimisa, ine zvinotevera maitiro:

1. Kushanda kwekuchengetedza mvura yepamusoro kunogona kurebesa nguva yekushanda kwedhaka rekuzvimisa, kuvandudza kusimba kwedhaka, kuwedzera simba rayo rekubatanidza, uye kushanda kwakanakisisa kwekubatanidza kwemvura kunogona kuderedza madota ekumhara.

2. Kubatana kwakasimba, kwakakodzera kumarudzi ose ezvivakwa zvekuvaka, dhaka rekuzvimiririra, kuderedza nguva yekunyura, kuderedza kuoma kwayo kuderera kwehuwandu, uye kudzivisa matambudziko akadai sekuputika uye kudhibha kwemadziro uye pasi.

3. Kudzivirira kubuda ropa, inogona kuita basa riri nani mukusimiswa, kudzivirira slurry kubva kune sedimentation uye nani kubuda ropa.

4. Chengetedza kushanda kwakanaka kwekuyerera, iyo yakaderera viscosity yehydroxypropyl methylcellulosehaizokanganise kuyerera kwe slurry, kuvakwa kuri nyore, chaiyo yakanaka yekuchengetedza mvura kuita, inogona kuburitsa yakanaka pamusoro pekuita mushure mekuzvidzivirira, uye kudzivirira kutsemuka munyaya yemadhiramu, iyo yakagadzikana yekubatanidza kuita kwe cellulose ether inovimbisa zvizere kuyerera kwakanaka uye kuzvidzora. -kugona kugadzirisa. Kudzora chiyero chekuchengetedza mvura kunogona kuita kuti isimbise nekukurumidza uye kuderedza shrinkage uye kuputika.
