Hpmc inosimudzira sei kuita kweiyo latex pendi?

HydroxyPropyl methylcellose (HPMC) ndiyo kiyi yekuwedzera muLatex Pendi yekupenda, ichiridza basa rekunetseka mukuwedzera mashandiro uye kunaka kwependi.

Nhanganyaya kune Latex Pendi
Pendix pendi, inozivikanwawo seAcrylic Pendi, inzira yakakurumbira yemvura-yakavakirwa pendi inoshandiswa zvakanyanya mune zvese zvekugara uye zvekutengesa zvinoshandiswa. Iyo ine pigment, mabhasi, solvent, uye dzakasiyana siyana. Playx Ples inosarudzwa nekuda kwekushandiswa kwavo kwekushandisa, kukurumidza kuoma nguva, uye zvakaderera zviyero zvehurongwa hwekugadzira mishonga (VOCS), kuita kuti vafarire zvine hushamwari.

Basa reHPMC mu Latex Pendi
HPMC ndeye isiri-ionic cellulose ether inotorwa kubva kune yakasikwa polymer cellulose. Iyo inoshandiswa zvakanyanya muLatex pendi yekufemerwa nekuda kweiyo yakanaka firimu-inoumba midziyo, kugona kwakasiyana, uye kugona kwemvura. Ngationgororei kuti Hpmc inosimudzira sei kuita kweLatex Paint:

1. Rheology shanduko:

HPMC inoita senge rheology modifier mune latex pendi mafomu, kudzora viscosity uye kuyerera maitiro ependi. Nekugadzirisa rheology, HPMC inovimbisa kudzvinyirira kwakakodzera, kusimbisa, uye roller application zvigadzirwa zvependi.
Kuwedzerwa kweHPMC kunobatsira kudzivirira kusimuka, kudonha, uye kutsvedza panguva yekunyorera, zvichikonzera patsime rakawanda uye hwakawanda hwakaguma.

2. Kuvandudza Kwekuchengeta Kwemvura:

HPMC inounza yakakwira mvura yekuchengetwa kwemvura, ichibvumira pendi yeLatex kuti irambe yakasimba uye kugadzikana nekufamba kwenguva.
Kugadziridzwa kwemvura kunoenderana nenguva yakawandisa yakavhurika nguva, iyo inoreva iyo nguva iyo iyo iyo pendi inoramba ichishanda mushure mekushandisa. Izvi zvinonyanya kubatsira mukunyorova kana zvinopisa zvinongedzo zvinokurumidza kuoma kunogona kuitika.

3. Kugadziriswa kwefirimu fomu:

HPMC AIDS mukuumbwa kweiyo yakasimba uye yunifomu firimu pane iyo substrate pamusoro. Iyo inovandudza kudenha yeiyo pendi kunzvimbo dzakasiyana siyana, kusanganisira yakaoma yakaoma, huni, simbi, uye kongiri.
Iyo firimu-inogadzira nzvimbo yeHPMC inobatsira kuimba yekusagadzikana, scrub kuramba, uye kusemesa kweiyo latex pendi, kuwedzeredza hupenyu hwayo hwebasa.

4. Anti-Spattering Etst:

HPMC inoderedza kupuruzira panguva yekunyorera application, zvichikonzera mukuchenesa uye zvakanyanya pendi pendi maitiro. Iyi yekupaza-inotsemuka mhedzisiro inonyanya kubatsira kana uchishandisa yakakwira-kumanikidza zvipfenyuro kana mhepo isina kupfira.

5. Kukudzika Kunowedzera:

HPMC inokanganisa iyo Latex pendi yekugadzira nekudzivirira pigment kugadzirisa, kuwanda, uye chikamu chekuparadzaniswa. Inokuchengetedza homogeneity ye pendi, ichiratidza kuti ruvara rwakaenderana nekuparadzaniswa kwemavara uye kuita.
Kuvandudzwa kugadzikana kunowedzera hupenyu hwesherufu hwe lalEx pendi, kuderedza marara uye kuisazve chigadzirwa mhando.

6. Voc Ressction:

Nekubatanidza HPMC muLELEX PASTEFICATION, Vagadziri vanogona kuderedza kuvimbika pane mishonga yechigadzirwa (voc) pasina kukanganisa. HPMC inogonesa kuumbwa kweiyo loc-voc kana zero-voc mapenda, kusangana nemitemo yezvakatipoteredza yezvakatipoteredza uye vatengi zvevatengi.

7.

HPMC inopa shanduko uye elasticity kune iyo yakaomeswa pendi yefirimu, ichidzora njodzi yekupaza, ichikanda, uye inobhururuka nekufamba kwenguva. Izvi zvinowedzera kusimba kwenguva refu uye kukwikwidza kwekunyora kwezvinhu zvakapendwa, kunyanya munzvimbo dzepamhepo dzakakwirira kana zvekunze zvekushandisa zvinoratidzwa nemamiriro ekunze ane hutsinye.

HPMC inotamba chikamu chemugari wenyika mukuvandudza mashandiro eAnalx Paint Fomu. Kubva kuRheology shanduko uye Kuchengetwa kwemvura kune firimu kuumbwa uye kugadzikana kugadzikana, HPMC kunobatsira kune huwandu hwakazara, kusimba, uye zvinyorwa zvekushandisa zveLatex pendi. Nekusimudzira mabhenefiti eHPMC, vagadziri vanogona kuburitsa mapepa ekuita-mashanduri anosangana nezvinodiwa zvevatengi vachitevedzera nemitemo yezvakatipoteredza.
