HPMC (ndiko kuti, hydroxypropyl methylcellulose) ndi yofunika kwambiri popanga zomatira zamatayilo.Imawonjezera kumamatira, kugwira ntchito komanso kusunga madzi kwa zomatira za matailosi.M'nkhaniyi, tikupatsani chiwongolero chokwanira chogwiritsira ntchito HPMC pazitsulo zomatira matayala.
1. Chiyambi cha HPMC
HPMC ndi non-ionic cellulose ether yomwe imapezeka mwa kusintha mapadi achilengedwe.Njira yopangirayi imaphatikizapo kuchitira cellulose ndi alkali kuti asungunuke, kenako ndikuwonjezera methyl chloride ndi propylene oxide kuti asinthe.Chotsatira chake ndi ufa woyera kapena wosayera womwe umasungunuka mosavuta m'madzi.
2. Makhalidwe a HPMC
HPMC ndi polima wosunthika kwambiri wokhala ndi zinthu zambiri zabwino kwambiri.Zina mwazofunikira zake ndi izi:
- Kusungidwa bwino kwa madzi
- kumatirira kwakukulu
- Kuwongolera makina
- Kupititsa patsogolo kukana kwa sag
- Kukana kutsetsereka kwamphamvu
- kuyenda bwino
- Maola otsegulira bwino
3. Ubwino wa HPMC mu ntchito zomatira matailosi
Ikagwiritsidwa ntchito popanga zomatira matailosi, HPMC imapereka zabwino zambiri kuphatikiza:
- Kusungidwa bwino kwa madzi kuti ntchito yomatira matayala ikhale yabwino m'malo onyowa
- Kuwongolera zomatira kuonetsetsa kuti matailosi akhazikika bwino
- Kuwongolera makina kumatsimikizira kugwiritsa ntchito mosavuta komanso kumachepetsa kuyesetsa komwe kumafunikira kuti pakhale malo osalala
- Amachepetsa kuchepa ndi kugwa, kukulitsa kukongola kwa malo a matailosi
- Imawongolera kusasinthika kwa zomatira matailosi, kulimbikitsa kugwiritsa ntchito moyenera komanso moyenera
- Kutetezedwa kowonjezereka kuti chitetezo chichuluke pamatayilo
4. Kugwiritsa ntchito HPMC mu Mapulogalamu Omatira Tile
HPMC imagwiritsidwa ntchito ngati thickener, zomatira, zosungira madzi ndi rheology modifier mu zomatira matailosi ntchito.Kawirikawiri amawonjezeredwa pa 0.5% - 2.0% (w / w) ya kusakaniza kowuma.Pansipa pali madera ena ofunika kugwiritsa ntchito HPMC.
4.1 Kusunga madzi
Zomatira za matailosi ziyenera kusiyidwa bwino kuti woyikayo akhale ndi nthawi yokwanira yokonza matailosi.Kugwiritsa ntchito HPMC kumapereka kusungirako bwino kwa madzi ndikuletsa zomatira kuti ziume mwachangu.Zimatanthauzanso kuti zomatira siziyenera kubwezeretsedwanso, zomwe zingayambitse kusagwirizana.
4.2 Kuwongolera kumamatira
The zomatira katundu HPMC kwambiri kumapangitsanso chomangira mphamvu ya zomatira matailosi.Zimathandizira kuonetsetsa kuti matailosi amakhalabe pamalo otetezeka, ngakhale m'malo okwera magalimoto kapena malo amvula.
4.3 Kuthekera
HPMC bwino workability wa zomatira matailosi, kukhala kosavuta kugwiritsa ntchito ndi kukwaniritsa pamwamba yosalala.Zimapangitsa zomatira kukhala zosavuta kupesa, kuchepetsa kuyesayesa kofunikira kukankhira zomatira pamwamba.
4.4 Chepetsani kuchepa ndi kugwa
M'kupita kwa nthawi, zomatira za matailosi zimatha kuchepa kapena kugwa, zomwe zimapangitsa kuti zisawonongeke komanso zosatetezeka.Kugwiritsiridwa ntchito kwa HPMC kumachepetsa kwambiri kuchepa ndi kuchepa, kuonetsetsa kuti yunifolomu ndi yokongola yomaliza.
4.5 Sinthani kukana kuterera
Kutsetsereka ndi kugwa ndizowopsa kwambiri pamatayilo, makamaka pakanyowa.Kulimbikira kukana kwa HPMC kumapangitsa zomatira zomwe zimagwiritsidwa ntchito kukhala zotetezeka komanso zimachepetsa chiopsezo cha kutsetsereka ndi kugwa.
5. Momwe Mungagwiritsire Ntchito HPMC mu Ma Tile Adhesive Applications
HPMC imawonjezedwa pamlingo wa 0.5% - 2.0% (w / w) wa osakaniza owuma.Iyenera kusakanikirana ndi simenti ya Portland, mchenga ndi ufa wina wouma ndi zina zowonjezera musanawonjezere madzi.M'munsimu muli masitepe omwe akugwiritsidwa ntchito pogwiritsira ntchito HPMC muzomatira zomatira.
- Onjezani ufa wouma pachidebe chosakaniza.
- Onjezani HPMC kusakaniza ufa
- Sakanizani ufa mpaka HPMC igawidwe mofanana.
- Pang'onopang'ono onjezerani madzi kusakaniza uku mukugwedeza mosalekeza kuti mupewe zotupa.
- Pitirizani whisk mpaka kusakaniza kuli kosalala komanso kukhala ndi mawonekedwe ofanana.
6. Mapeto
HPMC ndichinthu chofunikira kwambiri popanga zomatira matailosi, zomwe zimapereka zopindulitsa monga kumamatira kowonjezera, kusinthika kwachangu, ndikuchepetsa kuchepa ndi kugwa.Kugwiritsa ntchito HPMC mu zomatira matailosi kumafuna kusakaniza koyenera ndi mlingo kuti mupeze zotsatira zabwino.
Chifukwa chake, timalimbikitsa kwambiri kugwiritsa ntchito HPMC popanga zomatira matailosi kuti musangalale ndi zabwino zake ndikuwongolera mawonekedwe omalizidwa.
