Kuvaka-giredhi HPMC poda: chinhu chakakosha chemhando yepamusoro dhaka
Doka, chinhu chokuvakisa, chinoita basa rinokosha muzvirongwa zvokuvaka, zvichiita sechinhu chinobatanidza zvidhinha kana kuti matombo pamwe chete. Kuti uwane dhaka remhando yepamusoro, zvigadzirwa zvinofanirwa kusarudzwa nemazvo. Chimwe chinhu chinomira muindasitiri yedhaka ndeye hydroxypropyl methylcellulose poda, inowanzozivikanwa seHPMC.
HPMC ikomboni yepamberi ine zvivakwa zvakanakisa zvakakodzera kushandiswa mumasanganiswa edhaka. Mukuvaka, chinhu chakakurumbira, chakasiyana-siyana chinoshandiswa mukugadzirira kwevhu rakaoma rakasanganiswa semateiri anonamira, grouts uye stuccoes. HPMC poda inonzi modified cellulose ether yakagadzirwa nekemikari inogadzirisa cellulose. Iyo polymer inonyungudika mumvura inovandudza mashandiro ematokari emasoni nekusimudzira adhesion zvivakwa, kuchengetwa kwemvura, kubata kwesaiti uye kuvandudzwa kwemagetsi kuramba.
Ndeapi mabhenefiti ekushandisa HPMC yedhaka?
1. Wedzera zvinhu zvekunamatira
Kushanda kwepamusoro kweHPMC poda mukugadzirwa kwedhaka kunokonzerwa nekunaka kwayo kusunga zvinhu. Kana yakasanganiswa nemvura, HPMC inoumba gel inosunga uye inovandudza kuenderana uye kunamatira kwedhaka. Iyo yepamusoro chisungo pakati pedhaka uye substrate yakakosha kuve nechokwadi kugadzikana uye kusimba kwechimiro. HPMC inoumba chisungo chakasimba uye chakasimba chinodzivirira pamusoro kubva kunze kwezvinhu zvakadai sekunyorova uye kuchinja kwekushisa.
2. Yakanakisa kuchengetedza mvura
Iyo yakakwirira yekuchengetedza mvura yeHPMC poda inoita kuti ive yakakosha kuwedzera mukugadzirwa kwemateki emasoni. Kugona kweHPMC kusunga nekuchengetedza hunyoro mumusanganiswa wedhaka zvinoreva kuti dhaka rinoramba rakanyorova kwenguva yakareba panguva yekuvakwa. Iyo yakawedzerwa nguva yekuomesera inoita kuti chisungo chiporeswe zvizere uye chisimbiswe, ichipa mhedzisiro yakachengeteka uye inogara kwenguva refu.
3. Kuvandudza mabatirwo enzvimbo yekuvaka
HPMC poda inoshandura viscosity yedhaka, ichipa zvirinani kushanda uye nyore kushandisa panguva yekuisa. Shanduko yedhaka viscosity inoreva kuti zvinhu zvinogona kudururwa munzvimbo uye kuumbwa nekukurumidza uye nyore, kuderedza nguva yekuvaka uye kuwedzera kugona. Musanganiswa wakapfava unorevawo kushatirwa kushoma kwevashandi, kuwedzera kubereka uye kuderedza zvimedu, zvichikonzera mhedzisiro yakanaka muchikamu chekuvaka.
4. Kuvandudza kupikisa kwemagetsi
Iyo mechanical simba yedhaka inogadzirwa neHPMC poda yakakwirira kupfuura mamwe echinyakare edhaka zvigadzirwa. Iyo yakakwira mechanical kuramba yedhaka inoreva kuti zvinhu zvinogona kumirisana nemitoro yakanyanyisa, vibrations uye kupfeka pasina kuputika. HPMC poda inowedzera kusimba, flexural, compressive uye shear simba rematehwe, izvo zvose zvakakosha pakuvaka zvivako zvakasimba uye zvakagadzikana.
Kushandiswa kweHPMC poda mumhando dzakasiyana dzematehwe
1. HPMC inoshandiswa kugadzira dhaka rekupurasita
Stucco idhaka rinoshandiswa mukuvaka kupfeka, kudzivirira, kana kushongedza madziro uye sirin'i. HPMC poda chinhu chakakosha mukugadzirwa kwegypsum. Mapurasita akagadzirwa neHPMC poda ane yakanakisa adhesive zvivakwa, yakagadziridzwa kuchengetedza mvura, zvirinani kubata uye yakakwirira mechanical kuramba. HPMC chinhu chakakosha mukugadzirwa kwepurasita, sezvo inopararira zviri nyore uye inonamatira kune nzvimbo.
2. HPMC inoshandiswa kugadzira tile yekunamatira
Tile adhesive idhaka rakakosha rinoshandiswa kumadziro nekufukidzira pasi. Kuwedzera HPMC poda kumatairi anonamira kunonamira iyo inonamira yekubatanidza zvivakwa, inovandudza kuchengetedza kwemvura uye inonatsiridza inonamira mechanicha kuramba. HPMC-based tile adhesives inobvumira kupararira kuri nani, kunaka kwechisungo simba pakati petairi ne substrate, uye nguva refu yekushanda, izvo zvese zvakakosha pamhedzisiro yakanaka.
3. HPMC yekugadzira simende slurry
Grout idhaka rakatetepa rinoshandiswa kuzadza mikaha pakati pematairi kana zvidhinha. HPMC poda chinhu chakakosha mukugadzira simende slurries. HPMC grouts inopa yakagadziridzwa zvivakwa senge yakawedzera kuchengetwa kwemvura, kushanda kuri nani, kuenderana kuri nani, kuderedzwa kwekuseta nguva uye kuwedzera simba remagetsi. HPMC inovandudza kupedzisa kwekupedzisira kwegrout, ichipa yunifomu uye inoyevedza kutaridzika.
mukupedzisa
HPMC poda chinhu chakakosha mukugadzira dhaka remhando yepamusoro. Iyo ine mhedzisiro yakakosha pakuvandudza mashandiro ekubatanidza, simba rekuchengetedza mvura, kudzora nzvimbo yekuvaka uye kusimba kwemagetsi edhaka. HPMC ipolymer inonyungudika mumvura inogoneka uye inokodzera kushandiswa mumhando dzakasiyana dzematairi, seanonamira mataira, grouts uye stuccoes. Inosimudzira kusimba kwechisungo chedhaka, ichiita kuti chimiro chekupedzisira chive chakasimba, chakavimbika uye chinogara. Nyanzvi dzekuvaka dzinogona kuvimba neHPMC madhaka kuti agadzire anogara kwenguva refu uye anoyevedza madhaka ezvivakwa.
