Kuvaka Giredhi HPMC Self-leveling Compound

HPMC, kana Hydroxypropyl Methylcellulose, inonzi cellulose ether inoshandiswa zvakanyanya muindasitiri yekuvaka. Inowanzoshandiswa sechinhu chinowedzera mu-self-leveling compounds, izvo zvinhu zvinoshandiswa kuyera pasi zvisina kuenzana kana kugadzira nzvimbo yakatsetseka kune zvimwe zvinhu zvepasi.

Mishonga yekuzvimisa yega inowanzoshandiswa muzvirongwa zvekuvaka kuyera uriri husina kuenzana kana kuti hune nzvimbo dzakaderera. Aya makomisheni anowanzo gadzirwa kubva musanganiswa we simende, jecha, uye zvimwe zvinhu, uye anosanganiswa nemvura kugadzira mvura inodururwa. Kana yangodirwa pasi, musanganiswa unozvimisa unoyerera kuti ugadzire nzvimbo yakatsetseka, yakaenzana.

HPMC inowanzowedzerwa kune yega-leveling makomisheni kuti vavandudze mashandiro avo. Kunyanya, inobatsira kuvandudza kushanda kwekomboni, zvichiita kuti zvive nyore kudurura uye kupararira zvakafanana. Inobatsirawo kuderedza shrinkage uye kuputika panguva yekuomesa, uye inogona kuvandudza kusimba kwechisungo pakati pekomboni uye pasi pe substrate.

Kuvaka giredhi HPMC imhando chaiyo yeHPMC yakagadzirirwa kushandiswa mukuvaka maapplication. Inowanzo shandiswa mumakomisheni ekuzvimiririra, pamwe chete mune zvimwe zvekuvaka senge madhaka, grouts, uye stuccos.

Iyo chaiyo zvivakwa zvegiredhi rekuvaka HPMC inogona kusiyana zvichienderana nechigadzirwa chaicho uye mugadziri, asi kazhinji, ine zvinotevera maitiro:

Kuchengetedzwa kwemvura kwakakwirira: HPMC chinhu chinonzi hydrophilic, zvinoreva kuti ine hukama hwakasimba hwemvura. Iyi pfuma inobatsira kuvandudza kushanda kwemakomisheni ega-leveling, sezvo inobatsira kuchengetedza musanganiswa wakanyorova uye nyore kupararira.

Kugona kwakanaka kwekugadzira firimu: HPMC inogona kugadzira firimu rakatetepa pamusoro peiyo yega-leveling komisheni painooma, iyo inobatsira kunatsiridza simba rayo remuchina uye kusimba.

Kuvandudzwa kwekunamatira: HPMC inogona kuvandudza kunamatira kweiyo-yega-leveling komisheni kune iri pasi pe substrate, ichibatsira kugadzira yakasimba, yakasimba nzvimbo.

Yakaderedzwa shrinkage uye kuputika: HPMC inogona kubatsira kuderedza kuwanda kwe shrinkage uye kuputika kunoitika panguva yekuomeswa, izvo zvinogona kutungamirira kune yakawanda kunyange uye yakatsetseka pamusoro.

Isiri-chepfu uye ine hushamwari kwezvakatipoteredza: HPMC isiri-chepfu, ine hushamwari zvinhu zvakachengetedzeka kuti ishandiswe mukuvaka zvikumbiro.

Paunenge uchishandisa self-leveling makomisheni ane kuvaka giredhi HPMC, zvakakosha kutevedzera mirairo yemugadziri nemazvo. Musanganiswa unofanirwa kugadzirirwa maererano nehuwandu hwemvura-ku-upfu hunokurudzirwa, uye inofanira kusanganiswa zvakakwana kuti ive nechokwadi chokuti HPMC inoparadzirwa zvakaenzana mumusanganiswa wose.

Kana iyo komputa yekuzvimisa yadirwa pasi, inofanirwa kuparadzirwa uchishandisa trowel kana chimwe chishandiso kugadzira yakaenzana. Zvakakosha kushanda nekukurumidza, sezvo komboni ichatanga kugadzika mukati menguva pfupi.

Mushure mekunge komboni yapararira, inofanira kusiiwa kuti iome kwenguva yakakurudzirwa isati yaiswa zvimwe zvinhu zvepasi. Izvi zvichabatsira kuve nechokwadi kuti nzvimbo yacho yapora zvakakwana uye yakagadzirira kushandiswa.

Pakazere, giredhi rekuvaka HPMC chinhu chakakosha muindastiri yekuvaka, kunyanya mukuvandudza kwekuzvimiririra makomisheni. Hunhu hwayo hwakasiyana hunobatsira kuvandudza kushanda kwezvinhu izvi, zvichiita kuti zvive nyore kushanda nazvo uye zvakanyanya kusimba nekufamba kwenguva. Nekushandisa self-leveling makomisheni ane HPMC, nyanzvi dzekuvaka dzinogona kugadzira dzakatsetseka, nhanho nzvimbo dzakafanira kune dzakasiyana siyana dzepasi.
