Hukama huripo pakati peHPMC negrout yemataira

1. Nhanganyaya yeHydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC)imhando ye cellulose ether isingashandisi ionic inoshandiswa zvakanyanya muzvinhu zvekuvaka, mishonga, chikafu, makemikari ezuva nezuva uye mamwe maindasitiri. Yakagadzirwa nezvinhu zve polymer zvechisikigo kuburikidza nekuchinja kwemakemikari uye ine mvura inonyunguduka zvakanaka, inokora, inochengetedza mvura, inoita firimu uye inogadzikana. Mubasa rezvinhu zvekuvaka, HPMC inonyanya kushandiswa mudhaka rakaoma, kunamira mataira, upfu hweputty, grout, nezvimwewo kuvandudza mashandiro ekuvaka uye kuwedzera mhando yechigadzirwa chekupedzisira.

2. Basa uye kuumbwa kwegrout yemataira

Grout yemataira chinhu chinoshandiswa kuzadza mukaha uripo pakati pemataira, icho chine basa rekuwedzera runako, kusapinda mvura, kusabatwa nefungus uye kusabatwa nematombo. Zvinhu zvikuru zvegrout zvinosanganisira:
Simende kana resin: sechinhu chikuru chekubatanidza, chinopa simba nekuoma;
Chinozadza: chakadai sejecha re quartz, calcium carbonate, nezvimwewo, chinoshandiswa kuvandudza kuramba kupfeka uye kugadzikana kwechimiro che grout;
Zvinowedzerwa: zvakaita seHPMC, upfu hwelatex, pigment, nezvimwewo, zvinoita kuti grout ishande zvakanaka pakuvaka, irambe ichichengetedza mvura, irambe ichidzivirira kudonha kwemvura uye igare kwenguva refu.

3. Basa reHPMC mukugadzira mataira

Kunyangwe huwandu hweHPMC hunowedzerwa kugrout yemataira huri hudiki, basa rayo rakakosha, rinonyanya kuratidzwa muzvinhu zvinotevera:

(1) Kuchengetwa kwemvura

HPMC ine kugona kwakanaka kwekuchengetedza mvura. Mugrout, inogona kunonotsa kupwa kwemvura, kuwedzera kushanda zvakanaka kwesimende, kunyorovesa simende zvizere, kuvandudza kunamira uye kusimba kwegrout, uye kuderedza kutsemuka uye hupfu hunokonzerwa nekurasikirwa nemvura nekukurumidza.

(2) Kuvandudza mashandiro ekuvaka

HPMC inogona kuwedzera rheology yegrout, kuita kuti slurry ive nyore kusanganisa nekushandisa, kugadzirisa kutsetseka kwekuvaka, uye kudzivirira matambudziko akadai sekuungana uye kudzika kwemadziro panguva yekuvaka. Pamusoro pezvo, inogona kuwedzera nguva yekuvaka, ichipa vashandi nguva yakawanda yekugadzirisa nekuvandudza mhando yekuvaka.

(3) Dzivisa kutsemuka nekuderera kwesimba

Grout iyi inokurumidza kupwanyika uye kutsemuka nekuda kwekubuda kwemvura nekukurumidza panguva yekuoma kwayo. Kuchengetedza mvura kweHPMC kunogona kuderedza njodzi iyi zvinobudirira, kuchengetedza kugadzikana kwechimiro chegrout, kuderedza kugadzirwa kwema microcracks, uye kuvandudza grouting effect.

(4) Kuvandudza hunhu hwekudzivirira kudonha

Munguva yekuvaka yakamira (sekunge kuvharira madziro), chinhu chinovharira madziro chinowanzotsvedza kana kudonha nekuda kwesimba rinokwevera pasi. HPMC inogadzirisa hunhu hwe rheological hwechinhu chinovharira madziro uye inovandudza thixotropy yayo, kuitira kuti irambe iine viscosity yakakwira mumamiriro asina kusimba, uye inodzoreredza kuyerera kwemvura panguva yekushanda kwekugadzira kana kugadzira, nokudaro ichideredza dambudziko rekudonha uye inovandudza kushanda zvakanaka kwekuvaka.

(5) Kuvandudza kusimba kwemvura inonyunguduka uye kusimba kwemamiriro ekunze

HPMC inogona kuvandudza kugona kwemushonga wekudzivirira kutonhora nekunyunguduka, kuitira kuti ugare wakasimba munzvimbo dzine tembiricha yakaderera uye hausi nyore kuupfudza kana kudonha. Panguva imwe chete, inogona zvakare kuwedzera simba remushonga wekudzivirira kutonhora, kuitira kuti urambe uchishanda zvakanaka mumamiriro ezvinhu akaoma akadai sehunyoro nemwaranzi ye ultraviolet, uye kuwedzera hupenyu hwebasa rayo.

4. Zvinhu zvinokanganisa mashandiro eHPMC

Zvinhu zvakaita sehuremu hweHPMC, mwero wekutsiva, uye viscosity zvinokanganisa mashandiro ekupedzisira emushonga we caulking. Kazhinji:
Kukwidibira kwakanyanya kweHPMC kunogona kupa kukora kwakasimba uye kuchengetedza mvura, asi kunogona kuderedza kuyerera kwemvura;
Kushandiswa kwakakodzera kwechinhu chinotsiva (methoxy nehydroxypropyl content) kunogona kuwedzera kunyungudika uye kuve nechokwadi chekuti chinhu chinobvisa mvura chinowirirana;
Chipimo chakakodzera chinogona kuwedzera kushanda uye kugara kwenguva refu kwechinhu chinobata simbi, asi chiyero chakawandisa chinogona kukonzera kusviba kwakanyanya, zvichikanganisa kuvaka uye kukura kwesimba.

Sechinhu chakakosha chinowedzera mumidziyo yekubvisa mataira,HPMCinonyanya kuvandudza mhando yezvinonyungudutsa mvura nekuvandudza kuchengetwa kwemvura, kuvandudza mashandiro ekuvaka, uye kuwedzera kuramba kwekudzikira uye kugara kwenguva refu. Kusarudzwa kwakanaka kwemhando dzeHPMC uye mwero kunogona kuwedzera mashandiro ezvinonyungudutsa mvura, kuve nechokwadi chekuvakwa kwakatsetseka, uye kuwedzera mhedzisiro yekupedzisira yekushongedza nekudzivirira. Nokudaro, mukugadzira zvinonyungudutsa mvura, kusarudzwa nekushandiswa kweHPMC kwakakosha.
