Hukama pakati peHPMC uye tile grout

1. Nhanganyaya yeHydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC)isiri-ionic cellulose ether inoshandiswa zvakanyanya mukuvaka zvinhu, mishonga, chikafu, makemikari ezuva nezuva nemamwe maindasitiri. Yakagadzirwa nezvinhu zvakasikwa zvepolymer kuburikidza nekugadzirisa kemikari uye ine yakanaka kunyungudika kwemvura, kukora, kuchengetedza mvura, kugadzira firimu uye kugadzikana kwekumisa. Mumunda wezvivakwa zvekuvaka, HPMC inonyanya kushandiswa mudhaka rakaoma, tile inonamira, putty poda, grout, nezvimwe kuvandudza mashandiro ekuvaka uye kuwedzera kunaka kwechigadzirwa chekupedzisira.

2. Basa uye kuumbwa kwe tile grout

Tile grout chinhu chinoshandiswa kuzadza mukaha pakati pematairi, ane mabasa ekusimudzira aesthetics, kusapinda kwemvura, mildew resistance uye crack resistance. Izvo zvikamu zvikuru zvegrout zvinosanganisira:
Simende kana resin: sechinhu chikuru chekubatanidza, kupa simba uye kuoma;
Filler: sejecha re quartz, calcium carbonate, nezvimwewo, inoshandiswa kuvandudza kupfeka kuramba uye kugadzikana kwechimiro chegrout;
Zvekuwedzera: senge HPMC, latex poda, pigment, nezvimwewo, izvo zvinopa grout kuita kwakanaka kwekuvaka, kuchengetwa kwemvura, kushomeka kuramba uye kusimba.

3. Basa reHPMC mu tile grout

Kunyangwe huwandu hweHPMC hwakawedzerwa kune tile grout idiki, basa rayo rakakosha, rinonyanya kuratidzwa mune zvinotevera zvinhu:

(1) Kuchengeta mvura

HPMC ine yakanakisa kuchengetedza mvura. Mune grout, inogona kunonoka kubuda kwemvura, kuvandudza kushanda kwe hydration ye simenti, simiti yakazara hydrate, inonatsiridza kunamatira uye kusimba kwegrout, uye kuderedza kuputika uye upfu hunokonzerwa nekukurumidza kurasikirwa kwemvura.

(2) Kuvandudza kushanda kwekuvaka

HPMC inogona kukwidziridza rheology yegrout, kuita kuti slurry ive nyore kumutsa nekuisa, kuvandudza kutsetseka kwekuvaka, uye kudzivirira matambudziko akadai seagglomeration uye sagging panguva yekuvaka. Mukuwedzera, inogona kuwedzera nguva yekuvaka, ichipa vashandi nguva yakawanda yekugadzirisa nekuvandudza kunaka kwekuvaka.

(3) Dzivirira kuputika uye kupera

Iyo grout inowanzoita shrinkage uye kuputika nekuda kwekukurumidza kubuda kwemvura panguva yekuoma. Iyo yekuchengeta mvura mhedzisiro yeHPMC inogona kunyatso kudzikisa njodzi iyi, kuchengetedza kugadzikana kweiyo grout, kuderedza chizvarwa che microcracks, uye kugadzirisa grouting maitiro.

(4) Kuvandudza anti-sagging pfuma

Panguva yekuvaka kwakamira (sekunge kumadziro), iyo caulking agent inowanzotsvedza pasi kana kudonha nekuda kwegiravhiti. HPMC inogadzirisa rheological zvimiro zvecaulking agent uye inovandudza thixotropy yayo, kuitira kuti ichengetedze yakakwira viscosity munzvimbo yakadzikama, uye inodzoreredza fluidity panguva yekukurudzira kana yekuvaka mashandiro, nekudaro ichidzikisa dambudziko resag nekuvandudza kugona kwekuvaka.

(5) Natsiridza kutonhora-kunyungudika kuramba uye kuramba mamiriro ekunze

HPMC inogona kuvandudza kugona kwemumiriri wekumisa chando kutenderera, kuitira kuti irambe yakagadzikana munzvimbo dzakaderera tembiricha uye hazvisi nyore kuita hupfu kana kudonha. Panguva imwecheteyo, inogona zvakare kukwidziridza iyo caulking agent's mamiriro ekunze kuramba, kuitira kuti ikwanise kuchengetedza kuita kwakanaka pasi pemamiriro akaomarara senge humidity uye ultraviolet mwaranzi, uye kuwedzera hupenyu hwayo hwesevhisi.

4. Zvinhu zvinokanganisa kushanda kweHPMC

Maparamita akadai seHPMC's molecular weight, degree of substitution, uye viscosity inokanganisa kushanda kwekupedzisira kwecaulking agent. Kazhinji kutaura:
Yepamusoro viscosity HPMC inogona kupa yakasimba thickening uye kuchengetedza mvura, asi inogona kuderedza fluidity;
Dhigirii yakakodzera yekutsiva (methoxy uye hydroxypropyl yemukati) inogona kuvandudza solubility uye kuve nechokwadi chekufanana kweiyo caulking agent;
Yakakodzera dosage inogona kukwirisa kushanda uye kusimba kweiyo caulking agent, asi yakawandisa dosi inogona kutungamira kune yakawandisa viscosity, kukanganisa kuvaka uye kukura kwesimba.

Sekuwedzera kwakakosha mumatairi caulking agents,HPMCkunyanya inonatsiridza hunhu hwemacaulking agents nekuvandudza kuchengetwa kwemvura, kuvandudza mashandiro ekuvaka, uye kuwedzera shrinkage kuramba uye kusimba. Sarudzo inonzwisisika yemhando dzeHPMC uye dosages inogona kukwidziridza mashandiro evanokonzeresa, kuve nechokwadi chekuvaka kwakatsetseka, uye kuwedzera yekupedzisira yekushongedza nekudzivirira. Naizvozvo, mukugadzira dhizaini yematairi caulking agents, kusarudzwa uye kushandiswa kweHPMC kwakakosha.
