Muindasitiri yekuvaka, zvinonamira zvemataira zvakagadzirwa nesimende zvinoita basa rakakosha mukuona kuti pamusoro pemataira panogara kwenguva refu uye panogara kwenguva refu. Zvinonamira izvi zvakakosha pakubatanidza mataira zvakasimba kune zvinhu zvakaita sekongiri, dhaka, kana pamusoro pemataira aripo. Pakati pezvinhu zvakasiyana-siyana zvinonamira zvemataira zvakagadzirwa nesimende, hydroxypropyl methylcellulose (HPMC) inoonekwa sechinhu chakakosha nekuda kwehunhu hwayo hwakawanda uye mupiro wayo mukushanda kwehurongwa hwekunamira.
1. Nzwisisa HPMC:
Hydroxypropylmethylcellulose (HPMC) imhando ye cellulose ether isingashandisi ma polymers echisikigo, kunyanya cellulose. Inowanzoshandiswa muzvinhu zvekuvaka se rheology modifier, water retaining agent uye glue. HPMC inogadzirwa kuburikidza nekuchinja-chinja kwemakemikari kuita cellulose, zvichikonzera polymer inonyungudika mumvura ine hunhu hwakasiyana hwakakodzera kushandiswa kwakasiyana-siyana mukuvaka, mishonga uye chikafu.
2. Basa reHPMC mukunamira mataira kwakavakirwa pa simende:
Kuchengetedza Mvura: HPMC ine mukana wakanaka wekuchengetedza mvura, zvichiita kuti namatidziro irambe yakagadzikana uye ichishanda zvakanaka nekufamba kwenguva. Hunhu uhwu hwakakosha kudzivirira kuoma kwechinamatidziro nguva isati yakwana, kuve nechokwadi chekuti zvikamu zvesimende zvinonyoroveswa zvakakwana, uye kuwedzera simba rekubatana pakati petaira nepasita.
Kugadziriswa kweRheology: HPMC inoshandiswa senzira yekugadzirisa rheology, ichikanganisa maitiro ekuyerera uye kusimba kwezvinonamira zvemataira zvakagadzirwa nesimende. Nekudzora kusimba, HPMC inogona kuisa glue iri nyore, ichikurudzira kufukidza kwakaenzana uye kuderedza njodzi yekutsvedza kwemataira panguva yekuisa. Pamusoro pezvo, inobatsira kutsvedza kwakapfava uye inovandudza kupararira kweglue, nokudaro ichivandudza kushanda uye kuderedza simba rebasa.
Kunamira Kwakawedzerwa: HPMC inoshanda senamira, ichisimudzira kunamira pakati penamira nepamusoro petaira nepasi pevhu. Maumbirwo ayo emamorekuru anoita firimu rinonamira kana rakanyoroveswa, zvichinyatsobatanidza namira nezvinhu zvakasiyana-siyana, zvinosanganisira ceramics, porcelain, matombo echisikigo uye pasi pekongiri. Hunhu uhwu hwakakosha kuti pave nekunamira kwakasimba uye kwenguva refu, kudzivirira kupatsanurwa kwetaira uye kuve nechokwadi chekuti pamusoro petaira pari kugadzikana.
Kuramba Kutsemuka: HPMC inoita kuti kunamira kwemataira kwakavakirwa pasimende kuve nyore uye inovandudza kuramba kutsemuka. Nekuti mataira anogona kukanganiswa nekanika uye kufamba kwechimiro, kunamira kunofanirwa kunge kwakasununguka zvakakwana kuti kugadzikane nekufamba uku pasina kutsemuka kana kupatsanurwa. HPMC inowedzera kutsemuka kwemataira ekunamira, ichideredza mukana wekutsemuka uye ichivimbisa kugara kwenguva refu kwekuisa mataira, kunyanya munzvimbo dzine vanhu vakawanda kana nzvimbo dzinochinja tembiricha.
Kugara kwenguva refu uye Kuramba Mamiriro Ekunze: Kuwedzerwa kweHPMC kunowedzera kugara kwenguva refu uye kuramba mamiriro ekunze kwezvinonamira zvemataira zvakagadzirwa nesimende. Zvinowedzera kuramba kupinda kwemvura, kutonhora nekunyunguduka uye kusangana nemakemikari, kudzivirira kuora uye kuchengetedza kusimba kwepamusoro pemataira mukati nekunze. Pamusoro pezvo, HPMC inobatsira kuderedza mhedzisiro yekusagadzikana kwemamiriro ekunze, ichivimbisa kuti kuisa mataira kunoramba kwakanaka nekufamba kwenguva.
3. Mabhenefiti eHPMC muzvinonamira zvemataira zvakagadzirwa nesimende:
KUSHANDISA KWAKAVANDUDZWA: HPMC inovandudza mashandiro ekushandisa manamati emataira akavakirwa pasimende, zvichiita kuti zvive nyore kusanganisa, kuisa uye kupfava. Vagadziri vanogona kuwana mhedzisiro yakafanana pasina kushanda nesimba, vachichengetedza nguva nemari panguva yekuisa.
Simba reBond Rakawedzerwa: Kuvapo kweHPMC kunokurudzira kubatana kwakasimba pakati petaira, namira uye substrate, zvichikonzera kusimba kwebond kwakanyanya uye njodzi yekuparadzana kana kukundikana kwetaira inoderedza. Izvi zvinovimbisa kushanda kwenguva refu uye kugadzikana kwepamusoro petaira munzvimbo dzakasiyana-siyana.
Kuchinja-chinja: Zvinonamira zvemataira zvakagadzirwa neHPMC zvinogona kushandiswa zvakasiyana-siyana uye zvakakodzera kushandiswa pamhando dzakasiyana dzemataira, saizi uye substrates. Ingave iri kuisa mataira eceramic, porcelain, natural stone kana mosaic, makambani anogona kuvimba nezvinamira zveHPMC kuti zvipe mhedzisiro yakafanana kubva papurojekiti imwe kuenda kune imwe.
Kuenderana: HPMC inoenderana nezvimwe zvinowedzerwa uye zvinosanganiswa zvinowanzoshandiswa muma stimentitious tile adhesive, akadai se latex modifiers, polymers uye makemikari anowedzera mashandiro. Kuenderana uku kunobvumira maformula akagadzirwa kuti aenderane nezvinodiwa zvekushanda uye zvinodiwa papurojekiti.
Kugara kwenguva refu: HPMC inobva muzvinhu zvinogadziriswazve zve cellulose, zvichiita kuti ive sarudzo isingakuvadzi nharaunda yezvinhu zvekuvaka. Kuora kwayo uye kusakanganisa kwayakaita nharaunda zvinobatsira mukuvaka kwakasimba uye zvirongwa zvekuvaka zvine girini.
4. Kushandiswa kweHPMC mukunamira mataira kwakavakirwa pa simende:
HPMC inoshandiswa zvakanyanya mumhando dzakasiyana dzema tile akagadzirwa nesimende anosanganisira:
Dura Rakatetepa Rakajairika: HPMC inowanzoshandiswa mudura rakatetepa rakajairika rekubatanidza ceramics nemataira eceramic kune substrates dzakadai sekongiri, screeds uye cementitious backing boards. Hunhu hwayo hwekuchengetedza mvura uye kunamira hunoita kuti mataira emukati nekunze ashande zvakanaka.
Chinonamira Mataira Makuru: Muzvinhu zvinosanganisira mataira makuru kana mataira ematombo echisikigo anorema, zvinonamira zvakagadzirwa neHPMC zvinopa simba rakawedzerwa rekubatanidza uye kudzivirira kutsemuka, zvichienderana nehuremu uye hunhu hwetaira.
Zvinonamira Mataira Zvinochinjika: Kune zvinoshandiswa zvinoda kuchinjika uye kuchinjika, zvakaita sekuiswa pazvigadziko zvinofamba kana kukura, HPMC inogona kugadzira zvinonamira mataira zvinochinjika zvinogona kutsungirira kushushikana kwechimiro nemamiriro ekunze pasina kukanganisa kunamira, kugara kwenguva refu kana kugara kwenguva refu.
Hydroxypropyl methylcellulose (HPMC) inoita basa guru mukugadzirwa uye kushanda kwezvinonamira zvemataira zvakagadzirwa nesimende, zvichipa zvinhu zvakasiyana-siyana uye mabhenefiti anodiwa kuti mataira aiswe zvakanaka. Kubva pakuwedzera kunamira uye simba rekubatanidza kusvika pakuvandudza kushanda uye kugara kwenguva refu, HPMC inobatsira kuvandudza mhando, kuvimbika uye kugara kwenguva refu kwematanda eceramic mumapurojekiti akasiyana-siyana ekuvaka. Sezvo indasitiri yekuvaka ichiramba ichikoshesa kushanda zvakanaka, kugara kwenguva refu uye kushanda zvakanaka, kukosha kweHPMC mumatata emataira zvakagadzirwa nesimende kuchiri kukosha, zvichikurudzira hunyanzvi nekufambira mberi muhunyanzvi hwekuisa mataira.
