Hydroxypropyl methylcellulose (HPMC) isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nehurongwa hwemakemikari maitiro.Ihwo hupfu husina kunhuwa, husina muchetura uye husina chepfu hunoita hupfu hwakachena kana husina makore hushoma hwe colloidal mumvura inotonhora.Iyo ine thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, superficial, mwando-kuchengetedza uye inodzivirira colloid zvinhu.Hydroxypropyl methyl cellulose uye methyl cellulose inogona kushandiswa mukuvaka, indasitiri yependi, synthetic resin, indasitiri yeceramic, mushonga, chikafu, machira, zvekurima, makemikari emazuva ese uye mamwe maindasitiri.
Iko kushandiswa kukuru kwehydroxypropyl methylcellulose HPMC mune zvekuvaka:
1. Cement-based plaster
⑴ Natsiridza kufanana, ita kuti kupurasita kuve nyore kurovera, kunatsiridza kusagirira, kuwedzera kuyerera uye kupomba, uye kunatsiridza kushanda zvakanaka.
⑵ Kuchengetedzwa kwemvura yakakwira, kurebesa nguva yekuchengetera dhaka, kuvandudza kushanda zvakanaka, uye kufambisa hydration uye kusimba kwedhaka kuburitsa yakakwira mechani simba.
⑶ Chengetedza kuunzwa kwemhepo kubvisa mitswe pairi yekuputira uye kugadzira yakanakira nzvimbo yakatsetseka.
2. Gypsum-based plaster uye gypsum products
⑴ Natsiridza kufanana, ita kuti kupurasita kuve nyore kurovera, kunatsiridza kusagirira, kuwedzera kuyerera uye kupomba, uye kunatsiridza kushanda zvakanaka.
⑵ Kuchengetedzwa kwemvura yakakwira, kurebesa nguva yekuchengetera dhaka, kuvandudza kushanda zvakanaka, uye kufambisa hydration uye kusimba kwedhaka kuburitsa yakakwira mechani simba.
⑶ Dzora kuenderana kwedhaka kuti rigadzire rakanamira pamusoro pekuputira.
3. Masonry dhaka
⑴ Wedzera kunamatira nepamusoro pemasonry, simbisa kuchengetwa kwemvura, uye uvandudze kusimba kwedhaka.
⑵ Kuvandudza lubricity uye purasitiki, uye kuvandudza kuvaka;iyo dhaka yakagadziridzwa ne cellulose ether iri nyore kuvaka, inochengetedza nguva yekuvaka uye inoderedza mari yekuvaka.
⑶ Ultra-yakakwirira mvura-inochengetedza cellulose ether, yakakodzera zvidhinha zvinonwisa mvura.
4. Plate joint filler
⑴Kuchengeta mvura kwakanakisa, kurebesa nguva yekuvhura uye kunatsiridza kushanda zvakanaka.High lubricant, nyore kusanganisa.
⑵ Kuvandudza shrinkage kuramba uye kutsemuka kuramba, kunatsiridza coating pamusoro pemhando.
⑶ Kuvandudza kusungirirwa kwechisungo chepamusoro uye kupa chimiro chakatsetseka uye chakatsetseka.
5. Tile inonamira
⑴Kureruka kuomesa musanganiswa zvisanganiswa, hapana agglomeration, wedzera kukurumidza kwekushandisa, kunatsiridza mashandiro ekuvaka, chengetedza nguva yekushanda uye kuderedza mutengo wekushanda.
⑵ Nekuwedzera nguva yekuvhura, kushanda kwetiling kunogona kuvandudzwa uye yakanakisa adhesion athari inogona kupihwa.
6. Kuzvigadzika pasi zvinhu
⑴Ipa viscosity uye inogona kushandiswa senge anti-sedimentation yekuwedzera.
⑵Kuwedzera kupomba kwemvura uye kunatsiridza mashandiro ekugadzira pasi.
⑶ Chengetedza kuchengetwa kwemvura uye shrinkage, kuderedza kuputika uye kupera kwevhu.
7. Pendi yakagadzirwa nemvura
⑴Dzivirira kunaya kwemvura uye kurebesa hupenyu hwemudziyo wechigadzirwa.High biological kugadzikana, kuenderana kwakanakisa nezvimwe zvikamu.
⑵ Kuvandudza kuyerera kwemvura, kupa yakanaka anti-splash, anti-sagging uye kuenzanisa zvivakwa, uye simbisa yakanakisa kupera kwepamusoro.
8. Wallpaper Powder
⑴ Dissolve nekukurumidza pasina mapundu, izvo zvakanaka kusanganisa.
⑵ inopa yakakwira chisungo simba.
9. Yakawedzerwa simende bhodhi
⑴ Iine kubatana kwakanyanya uye lubricity, uye inosimudzira machinability ezvigadzirwa zvakaburitswa.
⑵ Kuvandudza simba rakasvibirira, kusimudzira hydration uye kurapa maitiro, uye kuwedzera goho.
10. Zvigadzirwa zveHPMC zvedhaka rakagadzirwa-yakasanganiswa
Chigadzirwa cheHPMC chinonyatso shandiswa dhaka rakagadzirwa-chakasanganiswa chine nani kuchengetedza mvura pane zvakajairwa mudhaka yakasanganiswa, kuve nechokwadi chekuti hydration yakakwana yezvinhu zvisingaite simende, uye nekudzivirira zvakanyanya kudzikiswa kwesimba rebhondi rinokonzerwa nekuwomeswa kwakanyanya uye kutsemuka kunokonzerwa nekuoma shrinkage.HPMC zvakare ine imwe mweya-entraining maitiro.Chigadzirwa cheHPMC chinonyatso shandiswa kudhaka yakasanganiswa ine huwandu hwakakodzera hwemhepo-yakadzidziswa, yunifomu uye mabhuru madiki emhepo, ayo anogona kuvandudza kusimba uye kutsetseka kwedhaka rakagadzirwa-musanganiswa.Iyo HPMC chigadzirwa chinonyatso shandiswa kugadzirira-musanganiswa dhaka ine imwe yekudzoreredza mhedzisiro, iyo inogona kurebesa nguva yekuvhurwa yedhaka yakasanganiswa uye kuderedza kuoma kwekuvaka.Hydroxypropyl methylcellulose (HPMC) isiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nehurongwa hwemakemikari maitiro.Ihwo hupfu husina kunhuwa, husina muchetura uye husina chepfu hunoita hupfu hwakachena kana husina makore hushoma hwe colloidal mumvura inotonhora.Iyo ine thickening, bonding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, superficial, mwando-kuchengetedza uye inodzivirira colloid zvinhu.Hydroxypropyl methyl cellulose uye methyl cellulose inogona kushandiswa mukuvaka, indasitiri yependi, synthetic resin, indasitiri yeceramic, mushonga, chikafu, machira, zvekurima, makemikari emazuva ese uye mamwe maindasitiri.
