HPMC, inozivikanwawo se hydroxypropyl methylcellulose, i polymer inoshanda zvakasiyana-siyana inoshandiswa mumaindasitiri akasiyana siyana, kusanganisira indasitiri yemapurasitiki. HPMC ndeye cellulose inotorwa nekemikari shanduko yeyakasikwa cellulose. HPMC inoshandiswa mumapurasitiki sechinhu chinoburitsa mold, softener, lubricant, uye zvimwe zvakawanda zvinoshandiswa. Ichi chinyorwa chichakurukura nezvekushandisa kwakawanda kweHPMC mumapurasitiki uye mabhenefiti avo uchidzivirira zvisiri izvo.
Plastics zvinhu zvekugadzira kana semi-synthetic zvinoshandiswa zvakanyanya mumhando dzakasiyana dzekushandisa nekuda kwekusiyana-siyana, kusimba uye kudhura-kushanda. Nekudaro, kugadzirisa uye kuumbwa kwemapurasitiki kunoda kushandiswa kwezvinowedzera senge zvinoburitsa maajenti, manyoro uye mafuta ekuzorisa zvivakwa zvavo uye nyore kugadzirisa. HPMC ndeye yakasikwa uye yakachengeteka yekuwedzera ine akawanda maapplication muindasitiri yemapurasitiki.
Imwe yemashandisirwo makuru eHPMC mumapurasitiki ndeyekuburitsa mold. HPMC inoita seyaimbova firimu, ichigadzira chipingamupinyi pakati pepurasitiki mold uye chigadzirwa chepurasitiki, ichidzivirira purasitiki kuti isanamatira kune mold. HPMC inosarudzwa pane mamwe echinyakare ekuburitsa mold agents sesilicone, wax, uye mafuta-based zvigadzirwa nekuti haina chepfu, haina kusvibisa, uye haina kukanganisa kutaridzika kwepasi kwezvigadzirwa zvepurasitiki.
Kumwe kushandiswa kwakakosha kweHPMC mumapurasitiki sechinhu chinopfavisa. Zvigadzirwa zvepurasitiki zvinogona kuoma uye zvinogona kunge zvisina kukodzera kune mamwe maapplication. HPMC inogona kushandiswa kugadzirisa kuomarara kwemapurasitiki kuti aite kuti anyanye kuterera uye akapfava. HPMC inowanzoshandiswa kugadzira mapurasitiki akapfava uye anochinjika, senge zvigadzirwa zvekurapa nemazino, matoyi uye zvinhu zvekurongedza chikafu.
HPMC zvakare mafuta anoshanda anogona kushandiswa kuvandudza epurasitiki kugadzirisa. Kugadziriswa kwepurasitiki kunosanganisira kudziyisa zvinhu zvepurasitiki uye kuzvibaya mu mold uye extruder. Munguva yekuita, zvinhu zvepurasitiki zvinogona kunamatira kumashini, zvichikonzera jamu uye kunonoka mukugadzirwa. HPMC irubricant inoshanda inogona kuderedza kupokana pakati pepurasitiki nemakina, zvichiita kuti kugadzirisa kwepurasitiki kuve nyore.
HPMC ine zvakawanda zvakanaka pamusoro pezvimwe zvinowedzera zvinoshandiswa mumapurasitiki. Semuyenzaniso, HPMC ine biodegradable uye ine hushamwari kwezvakatipoteredza, zvichiita kuti ive yakakodzera kushandiswa muzvigadzirwa zvinogara zviripo. HPMC hainawo chepfu uye haina njodzi dzehutano kuvashandi kana vatengi. Pamusoro pezvo, HPMC haina ruvara uye haina kunhuhwirira, zvichiita kuti ive sarudzo yakanaka kune zvigadzirwa uko kutaridzika uye kuravira kwakakosha, senge chikafu chekurongedza zvinhu.
HPMC inoenderana nezvimwe zvekuwedzera epurasitiki uye inogona kushandiswa pamwe chete nazvo kuwana izvo zvinodiwa. HPMC inogona kusanganiswa nemaplasticizer ekuchinjika, mafirita esimba, uye anosimbisa kusimba uye hupenyu hurefu. Iko kushandiswa kwakasiyana-siyana kweHPMC kunoita kuti ive yekuwedzera yakakosha mukugadzirwa kwemapurasitiki.
HPMC inoshandiswa zvakasiyana-siyana uye yakakosha yepurasitiki yekuwedzera. HPMC inoshandiswa mumapurasitiki sechinhu chinoburitsa mold, softener, lubricant, uye zvimwe zvakawanda zvinoshandiswa. HPMC ine akawanda mabhenefiti pamusoro pezvimwe zvinowedzera zvinoshandiswa mumapurasitiki, sekuve biodegradable, isiri-chepfu uye inoshamwaridzana nenharaunda. HPMC inopindiranawo nemamwe ekuwedzera epurasitiki uye inogona kushandiswa pamwe chete navo kuti uwane inodiwa zvivakwa. HPMC yakashandura indasitiri yemapurasitiki uye ingangoramba ichiita basa rakakosha mukuvandudza zvigadzirwa zvinogara uye zvine hushamwari.
