HPMC (Hydroxypropylmethylcellulose) inotorwa selulosi inowanzoshandiswa mukuvaka, kunyanya simende kana gypsum based plasters uye plasters.Icho chinowedzera chinowedzera chinowedzera chinowedzera kushanda kwezvinhu izvi uye inovandudza maitiro avo.HPMC imvura inonyungudika polima iyo inogona kuparadzirwa nyore nyore mumvura kuumba gobvu, homogeneous mhinduro.
Muchinyorwa chino, tinoongorora mabhenefiti akasiyana ekushandisa HPMC mune simende kana gypsum based plasters uye plasters.
Vandudza kushanda
Imwe yemabhenefiti makuru ekushandisa HPMC mune simende kana gypsum yakavakirwa plasters uye plasters ndiyo yakagadziridzwa kushanda kwayo.Kurongeka (Processability) zvinoreva nyore kusanganisa, kuiswa nekugadziriswa.HPMC inoshanda semafuta, inovandudza kuyerera uye kupararira kwechinhu, zvichiita kuti zvive nyore kuisa uye kupera kwakapfava.
Kuvapo kweHPMC mumusanganiswa zvakare kunoderedza kudiwa kwemvura yechinhu, iyo inobatsira kudzora kuderera uye kuputika panguva yekuomesa.Izvi zvinoreva kuti zvinhu zvichachengeta chimiro uye saizi uye hazvizotsemuka kana kuderera nekuda kwekurasikirwa nehunyoro.
Kuvandudza kunamatira
HPMC inogona zvakare kuvandudza kunamatira uye kupa simende kana gypsum yakavakirwa plasters kune iri pasi pevhu.Izvi zvinodaro nekuti HPMC inoumba firimu rakatetepa pamusoro peiyo substrate inoshanda senge inodzivirira hunyoro uye inodzivirira plaster kubva pakupepeta kana kuparadzaniswa kubva kune substrate.
Iyo firimu yakaumbwa neHPMC inowedzerawo chisungo chepurasita kune substrate nekugadzira chisimbiso chakasimba pakati pezviviri.Izvi zvinowedzera simba rose uye kusimba kwepurasita, zvichiita kuti isanyanya kutsemuka kana kuputsika.
Kuvandudza kusamira kwemamiriro ekunze
Simende kana gypsum based plasters nemapurasita ane HPMC anoshingirira kumamiriro ekunze nekukukurwa kwevhu.Izvi zvinodaro nekuti HPMC inoumba firimu rekudzivirira pamusoro peiyo plaster inodzinga mvura uye inodzivirira hunyoro kupinda mukati mechinhu.
Firimu rakaumbwa neHPMC rinoitawo kuti gypsum irambe yakasimba kune UV radiation uye mamwe marudzi emamiriro ekunze, ichidzivirira kubva pakukuvadzwa kunokonzerwa nezuva, mhepo, mvura nezvimwe zvakatipoteredza.
Kuwedzera kusimba
Kuwedzera HPMC kune simende kana gypsum based plasters uye plasters inovandudza kusimba kwavo kwese.Izvi zvinodaro nekuti HPMC inowedzera kuchinjika uye elasticity yepurasita, zvichiita kuti isanyanya kutsemuka kana kutyoka.HPMC inowedzerawo kupfeka uye kukanganisa kuramba kwezvinhu, zvichiita kuti zvirambe zvichirambana neabrasion.
Kuwedzera kusimba kwechinhu chacho kunoitawo kuti irambe ichidzivirira kukuvadzwa kwemvura sekupinda kwemvura, kunyorova uye kukura kwe mold.Izvi zvinoita kuti ive chinhu chakanakira kushandiswa munzvimbo dzakanyorova dzakadai sedzimba dzekugezera, kicheni uye dzimba dzepasi.
Kuvandudza kudzivirira moto
Simende- kana gypsum-based plasters uye mapurasita ane HPMC anonyanya kuramba kupfuura asina HPMC.Izvi zvinodaro nekuti HPMC inoumba chidziviriro pamusoro pepurasita iyo inobatsira kudzivirira kubva kubatidza kana kuparadzira murazvo.
Kuvapo kweHPMC mumusanganiswa zvakare kunovandudza kupisa kwemafuta eiyo plaster.Izvi zvinobatsira kudzivirira kupisa kusapinda papurasita, izvo zvinogona kubatsira kuderedza kupararira kwemoto.
mukupedzisa
HPMC chinhu chinowedzera chinowedzera chinoshandiswa zvakanyanya mukuvaka, kunyanya simende kana gypsum based plasters uye plasters.Inopa huwandu hwezvakanakira zvinosanganisira yakagadziridzwa processability, yakagadziridzwa adhesion, yakagadziridzwa mamiriro ekunze, yakagadziridzwa kusimba uye kuvandudzwa kwekudzivirira moto.
Kushandisa HPMC mune simende- kana gypsum-based plasters uye plasters kunogona kubatsira kuvandudza mashandiro uye hupenyu hurefu hwezvinhu izvi, zvichiita kuti zvisarambe kupfeka uye zvinhu.Yakanakira makondirakiti uye vavaki vanoda kuve nechokwadi chemhando uye kusimba kweprojekti yapera.
