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. Iine thickening, kusunga, kuparadzira, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, hunyoro-kuchengetedza uye inodzivirira colloid properties. Hydroxypropyl methylcellulose uye methylcellulose inogona kushandiswa mukuvaka zvinhu, pendi indasitiri, synthetic resin, ceramic indasitiri, mushonga, chikafu, machira, kurima, makemikari ezuva nezuva uye mamwe maindasitiri.
Chemical formula:
Hydroxypropylmethylcellulose (HPMC)[C6H7O2(OH)3-mn(OCH3)m(OCH2CH(OH)CH3)n]x
Iko kushandiswa kukuru kwehydroxypropyl methylcellulose HPMC mune zvekuvaka:
1. simende 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 nzvimbo yakanaka 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 Mortar
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. Panel 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 Adhesive ⑴Kureruka kuomesa musanganiswa zvinhu, hapana mapundu, kuwedzera kukurumidza kwekushandisa, kunatsiridza kuita kwekuvaka, kuchengetedza nguva yekushanda uye kuderedza mutengo wekushanda. ⑵ Nekuwedzera nguva yekuvhura, kushanda kwetiling kunogona kuvandudzwa uye yakanakisa adhesion athari inogona kupihwa.
6. Kuzvimisa-leveling pasi zvinhu ⑴ zvinopa viscosity uye zvinogona kushandiswa se anti-sedimentation additives. ⑵Kuwedzera kupomba kwemvura uye kunatsiridza mashandiro ekugadzira pasi. ⑶ Chengetedza kuchengetwa kwemvura uye shrinkage, kuderedza kuputika uye kupera kwevhu.
7. Pendi ine mvura ⑴Dzivisa kunaya kwemvura uye kurebesa upenyu hwemugaba wechigadzirwa. High biological kugadzikana, kuenderana kwakanakisa nezvimwe zvikamu. ⑵ Kuvandudza fluidity, ipa yakanaka anti-splash, anti-sagging uye yekuyera zvivakwa, uye simbisa yakanakisa kupera kwepamusoro.
8. Wallpaper powder ⑴ Dissolve nekukurumidza pasina mapundu, izvo zvakanaka kusanganisa. ⑵ inopa yakakwira chisungo simba.
9. Yakawedzera simende bhodhi (1) ine yakakwirira cohesiveness uye lubricity, uye inosimudzira machinability yezvigadzirwa zve extruded. ⑵ Kuvandudza simba rakasvibirira, kusimudzira hydration uye kurapa maitiro, uye kuwedzera goho.
10. Zvigadzirwa zveHPMC zvakatsaurirwa kune yakasanganiswa-yakavhenganiswa dhaka HPMC zvigadzirwa zvakatsaurirwa kudhaka-yakasanganiswa dhaka zvine mvura iri nani kuchengetwa mudhaka rakagadzirira-yakasanganiswa pane zvigadzirwa zvakajairika, kuve nechokwadi chekuyerera kwakakwana kwezvinhu zvisingasviki cementitious, kudzivirira zvakanyanya kuderedzwa kwesimba rebhondi rinokonzerwa nekuomeswa zvakanyanya. , uye Makorokoza anokonzerwa nekuomeswa kwemvura. 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 rakasanganiswa. Iyo HPMC chigadzirwa chinonyatso shandiswa kugadzirira-musanganiswa dhaka ine imwe yekudzoreredza mhedzisiro, iyo inogona kurebesa nguva yekuvhurwa yedhaka yakasanganiswa uye kuderedza kuoma kwekuvaka.
