Hydroxypropyl methylcellulose (HPMC) adhesives ave chinhu chakakosha mumabasa ekuvaka emazuva ano nekuda kwehunhu hwawo hwakanaka uye mashandisirwo akasiyana. HPMC inotorwa kubva ku cellulose uye ine yakanakisa adhesive zvivakwa pamwe nekukora, kuchengetedza mvura uye firimu-kugadzira mabasa. Muindasitiri yekuvaka, zvinonamira zveHPMC zvinoshandiswa mumhando dzakasiyana siyana dzekushandisa, kubva kumatairi anonamira, madhaka, uye plasters kune ega-leveling makomisheni.
1. Kushandiswa kweHPMC adhesive mukuvaka:
1.1 Tile inonamira:
HPMC inonamira chinhu chakakosha mune mataira anonamira mafomula, kuve nechokwadi chisungo chakasimba pakati petairi neiyo substrate.
Ivo vanosimudzira kushanda kweiyo adhesive tile kuitira nyore kushandisa uye kugadzirisa panguva yekuisa.
HPMC mabhainda anobatsira kuvandudza kuchengetwa kwemvura, kudzivirira kuoma nguva isati yakwana uye kuve nechokwadi chekuti hydration chaiyo yezvinhu simende.
1.2 Madhiri:
Mumatope, HPMC mabhainda anoita seanoshanda thickeners uye rheology modifiers, achivandudza kuenderana uye kushanda kwevhu musanganiswa.
Ivo vanovandudza kunamatira kwedhaka kune akasiyana ma substrates, anosanganisira kongiri, zvidhinha nedombo, nekudaro vachiwedzera iyo yakazara chisungo kusimba uye kusimba kwechimiro.
HPMC inonamira inobatsira kuderedza sag uye shrinkage yedhaka, ichibvumira kunyange kushandiswa uye kushomeka kwemarara.
1.3 Plaster:
HPMC inonamira inoita basa rakakosha mukuumbwa kwepurasita nekuda kwekuvaka kwavo kwakanaka uye kubatanidza zvivakwa.
Ivo vanobatsira mukushandiswa kweplaster coatings uku vachideredza kuputika nekuvandudza kupera kwepamusoro.
HPMC mabhainda anobatsira kusimudzira kuchengetwa kwemvura yemusanganiswa wegypsum, kukurudzira kurapwa kwakakodzera uye kudzivirira kuremara kwepamusoro senge efflorescence.
1.4 Kuzvimiririra makomisheni:
Mumakomisheni ekuzvimiririra, HPMC mabhandi anoita seanoshanda rheology modhifita, achipa iyo inodiwa kuyerera uye kuenzanisa zvivakwa kumusanganiswa.
Ivo vanobatsira kuwana yakatsetseka, kunyange pamusoro, ichiita kuti ive yakakodzera kune pasi pekushandisa.
HPMC inonamira inosimudzira kubatanidzwa uye kunamatira kwemakomisheni ega-leveling, kuve nechokwadi chisungo chakasimba kune substrate.
2. Zvakanakira zveHPMC adhesive mukuvaka:
2.1 Kusiyana-siyana:
HPMC anonamira anowanikwa mune akasiyana mafomati uye anogona kugadzirwa kuti asangane nezvinodiwa zvekushandisa.
Zvinogona kuiswa nyore nyore mumhando dzakasiyana-siyana dzekuvaka kuti dzipe zvinhu zvinodiwa pasina kukanganisa kushanda.
2.2 Kuvandudza processability:
Kushandiswa kweHPMC adhesives kunovandudza kushanda kwezvinhu zvekuvaka, zvichiita kuti zvive nyore kubata uye kushandisa.
Ivo vanowedzera kupararira uye kuvhurika nguva yekunamatira, zvichibvumira kuisirwa kwakanaka kwematairi, dhaka uye plasters.
2.3 Kuwedzera kusimba:
HPMC anonamatira anobatsira kusimba kwenguva refu kwezvinhu zvekuvaka nekuvandudza kunamatira kwavo, kubatana uye kuramba kune zvakatipoteredza zvinhu.
Ivo vanogona kuwedzera hupenyu hwechimiro nekudzikamisa matambudziko akadai sekutsemuka, shrinkage uye delamination.
2.4 Kuchengetedza kwezvakatipoteredza:
HPMC inonamira inzvimbo inoshamwaridzana neyakakomberedza kune yechinyakare inonamira zvinhu nekuti inotorwa kubva kune inovandudzwa chirimwa masosi.
Ivo vanopa kune yakagadzikana yekuvaka maitiro nekudzikisa yavo kabhoni tsoka uye nekuvandudza zviwanikwa zvekushandisa.
2.5 Tarisiro nebudiriro yeramangwana:
Nekukura kwekusimbisa kwemaitiro ekuvaka akasimba, kudiwa kwezvinhu zvine hushamwari zvekubatanidza zvinhu zvakaita seHPMC zvinotarisirwa kuwedzera.
Kuenderera mberi kwekutsvagisa nekusimudzira basa rine chinangwa chekuwedzera kuvandudza mashandiro uye kukodzera kweHPMC yekunamatira mukuvaka.
Kufambira mberi mukugadzira tekinoroji uye tekinoroji yekuwedzera inogona kutungamira mukuvandudzwa kwezvitsva zveHPMC zvekunamira zvigadzirwa zvine hunyanzvi hwekuita.
Hydroxypropyl methylcellulose (HPMC) adhesives anoita basa rakakosha mumabasa ekuvaka emazuva ano, achipa mhinduro dzakasiyana-siyana dzekushandisa kwakasiyana-siyana senge mataira anonamira, dhaka, plasters uye self-leveling makomisheni. Zvimiro zvavo zvakasarudzika zvinobatsira kuvandudza kushanda, kuwedzera kusimba uye kuchengetedzwa kwezvakatipoteredza kwemapurojekiti ekuvaka. Sezvo indasitiri yekuvaka iri kuramba ichishanduka, HPMC inonamira icharamba iri chinhu chakakosha mukutsvaga mhinduro dzekuvaka dzinoshanda, dzakasimba uye dzine hushamwari.
