Indasitiri yekuvaka idare rakakosha rinofukidza zviitiko zvakasiyana siyana kubva pakuvaka dzimba dzekugara kuvaka marapuro makuru ezvivakwa. Mune iyi indasitiri, kushandiswa kwezvakawanda zvakasiyana uye zvinhu zvinopindirwa nebasa rakakosha mukuvandudza mashandiro uye kuita kwekugadzira zvekuvaka. Hydroxyprishpropyl methylcellose (HPMC) inyaya yakakosha kwazvo. HPMC ndeye multifaunti compand ine akawanda mashandisiro ekushandisa mune yekuvaka chikamu nekuda kwezvinhu zvaro zvakasarudzika.
1.Chacracteristicistics ye hydroxypropyl methylcellose
Hydroxypronylmethylcellose ndeye semi-synthetic polymer inotorwa kubva ku cellulose. Iyo yakagadzirwa kuburikidza nemakemikari kugadziridzwa kwemheremalose, kunyanya nekuibata neProfyeryxo oxide uye methyl chloride. Maitiro acho anogadzira makomendi ane huwandu hwakasiyana idzo dzinovaita kuti vave vakakodzera kune dzakasiyana siyana dzekuvaka.
Kuchengeta kwemvura: imwe yeiyo yakakosha zvivakwa zveHPMC ndeyekugona kuita kuti ive yemvura. Ichi chivakwa chakakosha muzvinhu zvekuvaka senge motsi, uko kuchengetwa kwemvura kunobatsira kuwedzera kushanda kwemusanganiswa, kubvumira kuvaka kuri nani uye kupedzisa.
Kukakavara: HPMC inoita seyekuita mumiririri wakakura mukuvaka mafambiro. Nekuwedzera iyo visikopo yezvinyorwa, inovandudza kuenderana kwayo uye kugadzikana, nekudaro inosimudzira mashandiro ayo panguva yekushandisa.
ADHesion: HPMC inovandudza kuderedza kwezvivakwa zvekuvakira kune substrate, kusimudzira zviri nani kusungwa uye kuderedza njodzi yekushomeka kana kuseka.
Film Fialation: HPMC Dries kuti iite firimu rakatetepa, rinochinja-famba rinopa chisungo chedziviriro pamusoro pechiso. Ichi chivakwa chinonyanya kubatsira mumatombo uye pendi kuti uwedzere kusimudzira uye kuramba kune zvinhu zvakatipoteredza.
2. Kushandiswa kwehydroxyprupyl methylcellose mukuvaka
Iyo inopesana neHPMC inozvikweretesa pachayo kune dzakasiyana siyana dzekushandisa muindasitiri yekuvaka. Zvimwe zvakakosha zvikumbiro zvinosanganisira:
Tile Adhirelives uye Grouts: HPMC inowanzoshandiswa mumatanda inonamira uye magirinari ekuvandudza basa ravo, kudenha uye nekuchengetwa kwemvura. Izvo zvinobatsira kudzivirira kutsvage uye kupaza uchisimudzira chisungo pakati peiyo til uye substrate.
Simende plasters uye plasters: mumapuranga emapuranga uye plasters, hpmc is kiyi inowedzera kudzora kusarudzika uye kuvandudza kushanda. Inoita kuti application inotsvedza uye inoderedza sagging kana kutsvedza kwechinyorwa.
Kuzvimiririra mishonga: HPMC inowanzo kubatanidzwa mukuzvimiririra makomputa ekuzvimiririra kugadzirisa kwavo kuyerera zvivakwa uye kudzivirira kuunganidzwa. Izvi zvinoburitsa nzvimbo yakatsiga, yakaenzana yakakodzera yekuisa pasi pekuisa pasi.
Kunze kwekunzwa uye kupedzisa masisitimu (eifs): Eifs): Eifs anovimba neHPMC-based ainesoms inonamatira uye kuunganidzira insolation pane iyo substrate uye inopa kupedzisa. HPMC inokwidziridza kusimba uye kupokana kwemamiriro ekunze kweiyo eifs system, ichisimudzira hupenyu hwebasa rayo.
Gypsum Zvigadzirwa: HPMC inoshandiswa mune zvigadzirwa zveGypsum zvakadai sezvinobatanidzwa zvakabatana uye stucco kuvandudza kushanda, kushamwaridzana uye kupenga kuramba. Izvo zvinovandudzawo kupedzisa kwemusoro uye kusungwa kwezvinhu zveplaster.
3. Zvakanakira uchishandisa hydroxyprupyl methylcellose mukuvaka
Kushandiswa kweHPMC kunopa nyanzvi dzekuvaka nekubatsirwa kwakawanda, kusanganisira:
Kuvandudzwa Kurovedza: HPMC inovandudza kushanda kwezvinhu zvekuvakisa, kuita kuti vakuve nyore kubata, vashandise uye kupedza. Izvi zvinowedzera kubereka uye kuderedza mari yemutengo.
Kuwedzera Kubata: HPMC Zvivakwa zveHPMC zvinobatsira kuvandudza maitiro ekuita sekududzira, kuchengetwa kwemvura uye kusimba, zvichikonzera mhedzisiro yemhando yepamusoro.
Kuenderana: HPMC inoenderana nezvimwe zvakasiyana zvezvimwe zvinhu zvekuvaka uye zvinowedzera, uchibvumira zvinhu zvakasiyana siyana zvinosangana chaizvo neyechokwadi Project Project zvinodiwa.
Kutsigirwa kwezvakatipoteredza: HPMC inotorwa kubva kune imwe nzvimbo yekuvandudza cellulose maseru uye ndeye biodegradable, ichiita kuti isimbe yakasimba yekuvaka yekuvaka.
Mutengo - Kubudirira Kwekutanga: Nepo mutengo wekutanga weHPMC zvinogona kunge zvichikwira zvichienzaniswa nezvetsika zvekuwedzera, kuita kwayo uye zvakanakira zvakanaka zvinowanzo kururamisa iyo investment munguva refu.
Hydroxyprupyl methylcellose inoita basa rekuvaka mune yekuvaka indasitiri, nezvinhu zvakasarudzika uye zvakanaka zvinobatsira kugadzirisa basa, kusimba uye kusimba kwekuvaka uye masisitimu ekuvaka uye masisitimu. Kubva mukuvandudza kushanda uye kusimudzira kuwedzeredza kuchengetwa kwemvura uye kujaira, HPMC yave yakavanzika yekuwedzera muzvivakwa zvekuvaka. Kusiyana kwekuvaka kwakasiyana. Sezvo indasitiri yekuvaka ichiramba ichishanduka, inoda HPMC inotarisirwa kukura, inotungamirwa nekuda kwekushanda kwakakwirira, kwakasimba. Naizvozvo, zvakare kutsvagisa uye kusimudzira mukuvandudzwa uye kushandiswa kweHPMC kunodiwa kuti usangane nezvinodiwa zvekuvaka zvenzvimbo dzekuvaka.
