HPMC (hydroxypropyl methylcellulose) is cellulose-based nonionic polymer inoshandiswa zvakanyanya mukuvaka, chikafu uye maindasitiri emishonga. Mundima yekuvaka, HPMC inonyanya kushandiswa seyakakora, inochengetedza mvura, inonamira uye rheology modifier mune ceramic tile inonamira maumbirwo. HPMC inoita basa rakakosha mukuvandudza kutsvedza kuramba uye nguva yakavhurika yematairi anonamira maumbirwo.
Slip resistance inoreva kugona kwekunamira kwetaira kuchengetedza simba rekugera rinodiwa kuti rirambe kusimuka pasi pemutoro chaiwo. Mune mamwe mazwi, kutsvedza kuramba ndiko kubata kwetira pane substrate. Tile inonamira inofanirwa kuve yakanaka kutsvedza kuramba kuti ive nechokwadi chekuti mataira anogara akachengeteka munzvimbo panguva uye mushure mekuiswa. Chikonzero chikuru chekusakwana kutsvedza kuramba ndiko kushaikwa kwekunamatira pakati pekunamatira uye substrate. Apa ndipo apo HPMC inoita basa rakakosha mukugadzira mataira anonamira.
HPMC inoshanda seyakakora uye inochengetedza mvura mumiriri mune mataira anonamira maumbirwo. Inovhara kufamba kwemvura mukati mekunamatira, nekudaro ichiwedzera viscosity yayo uye nekudaro kutsvedza kuramba. HPMC inopawo yakaonda, yunifomu, inoenderera firimu pakati pe tile uye substrate. Iyo firimu inoumba bhiriji pakati pezviso zviviri, ichigadzira kushamwaridzana kwepedyo uye kuwedzera kunamira kwekubata pane tile.
HPMC inokwidziridzawo kusimba kwesimba uye elongation zvivakwa zvematairi anonamira. Izvi zvinoreva kuti kana mutoro ukaiswa kumataira, HPMC-ine inonamira inokonzeresa zvakanyanya isati yatsemuka, nekudaro ichiwedzera kugona kwese kweanonamira kuramba kutamiswa.
Nguva yakavhurika inoreva nguva yekuti tile yekunamatira inoramba ichishanda mushure mekushandisa. Ichi chinhu chakakosha mumatairi ekunamira mafomula nekuti inobvumira mugadziri nguva yakakwana yekugadzirisa tira pamberi pekunamatira kuoma. HPMC inowedzera iyo yakavhurika nguva yekunamira mataira nekuita senge rheology modifier.
Rheology chidzidzo chekuti zvinhu zvinofamba sei uye zvinokanganisa. Tile adhesive formulations inofanirwa kuve neyakananga rheology kuchengetedza kushanda uye kunamatira. HPMC inoshandura rheology yematairi adhesive formulations nekukanganisa viscosity yavo, thixotropy, uye plasticity. HPMC inowedzera viscosity yekunamatira mataira, ichiita kuti iome uye iite shoma. Kuyerera kunononoka kunoita kuti kunamira kuve nyore kugadzira uye kuumba, izvo zvinobatsira kuwedzera nguva yakavhurika. HPMC inogona zvakare kusimudzira iyo thixotropy yematairi adhesives. Thixotropy ndiko kukwanisa kwekunamatira kudzokera kuviscosity yayo yepakutanga mushure mekuvhiringidzika. Izvi zvinoreva kuti HPMC-ine maadhesives haadiki kupatsanurwa kana sag mushure mekushanduka uye anogona kudzoserwa kune serviceability kwenguva yakareba.
HPMC inovandudza mapurasitiki e ceramic tile adhesive. Plasticity inoreva kugona kwenamira kuti irambe ichishanda pasi pekusiyana kwetembiricha uye mwando. Zvinamira zvine HPMC hazvikanganiswe nekushisa uye humidity kuchinja uye kuchengetedza kushanda kwavo uye kunamatira zvivakwa. Iyi purasitiki inovimbisa kuti tile yekunamatira inoramba ichishandiswa mukati mehupenyu hwayo hwesevhisi uye haizotsemuka kana kuparadzaniswa kubva kune substrate.
Basa reHPMC mumatairi anonamira maumbirwo ekuwedzera kutsvedza kuramba uye nguva yakavhurika yakakosha. Inoita seyakakora, inochengetedza mvura, inonamira, rheology modifier, uye inovandudza kusimba kwesimba, kurebesa uye purasitiki yekunamatira mataira. Zvinamira zvine HPMC zviri nyore kushandisa, zvinogadziriswa, uye zvinochengetedza kunamatira mukati mehupenyu hwavo hwesevhisi. Kushandiswa kwayo kwakapararira mumhando dzakasiyana siyana dzekuvaka kunoratidza kuti yakachengeteka, inogoneka uye inodhura.
HPMC chinhu chakakosha mukugadzira mataira anonamira maumbirwo ekuwedzera kutsvedza kuramba uye kuvhurika nguva. Zvimiro zvaro zvinoita kuti zvive zvakanaka kune vanogadzira mataira anonamira uye makondirakiti anoda adhesive formulations ane workability, kubatana uye yakasimba bonding zvivakwa. HPMC saka inopa mupiro wakanaka kune zvivakwa zvemazuva ano uye inopa mabhenefiti akawanda pasina kukanganisa nharaunda kana hutano hwevanhu.
