HPMC (kureva, hydroxypropyl methylcellulose) chinhu chakakosha mukugadzirwa kwematairi anonamira. Iyo inosimudzira kunamatira, kushanda uye kuchengetwa kwemvura kwematairi ekunamatira. Muchikamu chino, tichakupa gwara rakazara rekushandisa HPMC mumatairi ekunamira maapplication.
1. Nhanganyaya kuHPMC
HPMC is a non-ionic cellulose ether inowanikwa nekugadzirisa serurosi chaiyo. Maitiro ekugadzira anosanganisira kurapa cellulose nealkali kuinyungudutsa, wobva wawedzera methyl chloride uye propylene oxide kuigadzirisa. Mhedzisiro ihwo hupfu huchena kana husina-chena hunonyungudika mumvura.
2. Hunhu hweHPMC
HPMC i polymer inoshanda zvakasiyana-siyana ine zvakawanda zvakatanhamara zvivakwa. Zvimwe zvezvimiro zvayo zvakakosha zvinosanganisira:
- Yakanakisa kuchengetedza kwemvura
- kunamatira kwepamusoro
- Enhanced machinability
- Kuvandudza sag resistance
- Kuwedzera kutsvedza kuramba
- kufamba kwakanaka
- Maawa ekuvhura akavandudzwa
3. Zvakanakira HPMC mune tile adhesive application
Kana ichishandiswa mukugadzira mataira ekunamira, HPMC inopa akawanda mabhenefiti anosanganisira:
-Kuchengetedzwa kwemvura kurinani kwekuvandudzwa kwematairi adhesive kuita munzvimbo dzine mvura
- Yakanatsiridzwa yekunamira zvivakwa kuti ive nechokwadi chekuti mataira abatwa zvakasimba munzvimbo
-Kunatsiridza machinability kunoita kuti kuve nyore kwekushandisa uye kuderedza kuedza kunodiwa kuti uwane nzvimbo yakatsetseka
- Inoderedza shrinkage uye sagging, inosimudzira aesthetics yenzvimbo dzemataira
- Inovandudza kuenderana kwematairi anonamira, inosimudzira kunyange uye iko iko kushandisa
- Yakakwidziridzwa kutsvedza kuramba kwekuwedzera kuchengetedzeka pane mataira nzvimbo
4. Kushandiswa kweHPMC muTile Adhesive Applications
HPMC inoshandiswa seyakakora, inonamira, inochengetedza mvura uye rheology modifier mumatairi anonamira maapplication. Inowanzowedzerwa pa 0.5% - 2.0% (w / w) yemusanganiswa wakaoma wakaoma. Pazasi pane dzimwe nzvimbo dzinokosha dzekushandisa HPMC.
4.1 Kuchengeta mvura
Iyo tile yekunamatira inoda kusiiwa yakasimba kuitira kuti mugadziri ave nenguva yakakwana yekugadzirisa tile. Iko kushandiswa kweHPMC kunopa yakanakisa kuchengetedza kwemvura uye kunodzivirira kunamira kubva pakuoma nekukurumidza. Zvinoreva zvakare kuti iyo yakanamatira haidi kudzoreredzwa, izvo zvinogona kutungamirira kukusaenderana kwekuita.
4.2 Kuvandudza kunamatira
Iyo inonamira zvimiro zveHPMC inosimudzira zvakanyanya kusimba kwechisungo chekunamatira mataira. Inobatsira kuve nechokwadi chekuti tile inogara yakachengeteka munzvimbo, kunyangwe munzvimbo dzakakwirira dzemotokari kana nzvimbo dzakanyorova.
4.3 Machinability
HPMC inovandudza kushanda kwematairi anonamira, zvichiita kuti zvive nyore kuisa uye kuwana nzvimbo yakatsetseka. Inoita kuti kunamira kuve nyore kupeta, kuderedza kushanda kunodiwa kusundira chinonamira pamusoro.
4.4 Deredza kuderera uye kusaga
Nokufamba kwenguva, tile yekunamatira inogona kuderera kana kunyungudika, zvichiita kuti pave nekuguma kusina kunaka uye kusina kuchengeteka. Iko kushandiswa kweHPMC kunoderedza zvakanyanya shrinkage uye sagging, kuve nechokwadi cheunifomu uye inoyevedza kupera.
4.5 Kuvandudza kutsvedza kuramba
Kutsvedza nekudonha injodzi huru pane mataira, kunyanya kana pakanyorova. Iyo yakakwidziridzwa kutsvedza kuramba kweHPMC inoita kuti mataira anonamira ashandiswe akachengeteka uye anoderedza njodzi yekutsvedza uye kudonha.
5. Mashandisiro Ekushandisa HPMC muTile Adhesive Applications
HPMC inowanzowedzerwa pachiyero che 0.5% - 2.0% (w / w) yemusanganiswa wakaoma. Inofanira kunge yakasanganiswa nePortland simenti, jecha uye humwe hupfu hwakaoma uye zvimwe zvinowedzera usati wawedzera mvura. Pazasi pane matanho anosanganisirwa mukushandisa HPMC mune mataira adhesive application.
- Wedzera hupfu hwakaoma mumudziyo wekusanganisa.
- Wedzera HPMC kumusanganiswa wehupfu
- Kurudzira musanganiswa wehupfu kusvika HPMC yagovaniswa zvakaenzana.
- Zvishoma nezvishoma wedzera mvura kumusanganiswa uchingo kurunga nguva dzose kudzivirira mapundu.
- Ramba uchipuruzira kusvikira musanganiswa watsetseka uye une yunifomu inofanana.
6. Mhedziso
HPMC chinhu chakakosha mukugadzirwa kwematairi anonamira, ichipa mabhenefiti akakosha akadai sekusimudzira kunamatira, kugadziridzwa kugadzirisika, uye kuderedzwa shrinkage uye sagging. Kushandisa HPMC mumatairi ekunamira maapplication kunoda kusanganisa kwakaringana uye dosage kuti ive yakakwana mhedzisiro.
Nokudaro, isu tinokurudzira zvakasimba kushandiswa kweHPMC mukugadzirwa kwematairi ekunamatira kuti inakidzwe nezvakanaka zvayo uye kuvandudza kunaka kwepamusoro pekupedzisira.
