Basa re hydroxyethyl cellulose mupende yematombo chaiwo

Nhanganyaya kupende yematombo chaiwo

Pendi yematombo chaiwo ipende ine maitiro ekushongedza akafanana negranite uye marble. Pendi chaiyo yedombo inonyanya kugadzirwa nehupfu hwematombo emhando dzakasiyana siyana, uye inoshandiswa kune yekutevedzera ibwe mhedzisiro yekuvaka ekunze madziro, anozivikanwawo sedombo remvura.

Zvivako zvakashongedzwa nependi yematombo chaiyo zvine ruvara rwechisikigo uye chechokwadi, zvichipa vanhu runako, runako uye rwakaremerwa runako, rwakakodzera kushongedza kwemukati nekunze kwezvivakwa zvakasiyana-siyana, kunyanya pazvivakwa zvakakomberedzwa, zvakajeka uye zvakaita sehupenyu.

Pendi chaiyo yematombo ine hunhu hwekudzivirira moto, kusapinda mvura, asidhi uye alkali kuramba, kuramba kusvibiswa, kusiri muchetura, kunhuhwirira, kunamatira kwakasimba, uye kusambopera. Iyo pendi ine yakanaka adhesion uye kutonhora-kunyungudika kuramba, zvichiita kuti kunyanya kukodzera kushandiswa munzvimbo dzinotonhora.

Pendi chaiyo yematombo ine zvakanakira kuomesa nyore, kuchengetedza nguva uye kuvaka kuri nyore.

Basa re hydroxyethyl cellulose mupende yematombo chaiwo

1 shoma rebound
Hydroxyethyl cellulose mupende chaiyo yematombo inogona kudzivirira kupararira kwakanyanya kweibwe chaiyo pendi poda, kuwedzera nzvimbo yekuvaka inoshanda, kuderedza kurasikirwa uye kusvibiswa kwezvakatipoteredza.

2 Kuita zvakanaka
Mushure mekushandisa hydroxyethyl cellulose kugadzira zvigadzirwa zvepende chaiyo yematombo, vanhu vanonzwa kuti chigadzirwa chine viscosity yakakwirira uye kunaka kwechigadzirwa kunovandudzwa.

3. Yakasimba inopesana nekupinda mukati meiyo topcoat
Iyo chaiyo dombo pendi chigadzirwa chakagadzirwa nehydroxyethyl cellulose ine chimiro chakaomarara, ruvara uye gloss yetopcoat inofanana panguva yekuvaka, uye huwandu hwetopcoat huchadzikiswa. Mushure mekukora kwechinyakare (senge: alkali kuzvimba, zvichingodaro) inogadzirwa kuita pendi chaiyo yematombo, nekuda kwechimiro chayo chakasununguka mushure mekuvaka nekuumbwa, uye nekuda kwekukora uye chimiro chekuvaka, kushandiswa kwependi panguva yetopcoat kuchaita. wedzera zvinoenderana, uye Pane musiyano mukuru mukutorwa kwependi yepamusoro.

4. Kuramba kwakanaka kwemvura uye firimu-kugadzira maitiro
Iyo chaiyo dombo pendi yakagadzirwa hydroxyethyl cellulose ine yakasimba chigadzirwa adhesion uye zvakanaka kugarisana pamwe emulsions, uye chigadzirwa firimu rinowedzera dense uye tsindirana, nokudaro kuvandudza ayo mvura kuramba uye zvinobudirira kudzivirira kuitika chena mumwaka wekunaya.

5 Yakanaka anti-kunyura maitiro
Iyo chaiyo pendi yedombo yakagadzirwa ne hydroxyethyl cellulose ichava neiyo yakakosha network dhizaini, iyo inogona kunyatso kudzivirira hupfu kubva pakunyura, kuchengetedza chigadzirwa chakagadzikana panguva yekufambisa uye kuchengetedza, uye kuwana yakanaka inogona kuvhura mhedzisiro.

6Kuvaka kuri nyore
Iyo chaiyo pendi yematombo yakagadzirwa nehydroxyethyl cellulose ine imwe fluidity panguva yekuvaka, izvo zvinoita kuti zvive nyore kuchengetedza iwo mavara panguva yekuvaka, uye haidi hunyanzvi hwekuvaka.

7 Yakanakisa mildew resistance
Iyo yakakosha polymeric chimiro inogona kunyatso kudzivirira kupinda kwe mold. Zvinokurudzirwa kuwedzera huwandu hwakakodzera hwebhaktericidal uye antifungal agent kuti ive nechokwadi chekuita zviri nani.
