Muzvinhu zvekuvaka zvemazuva ano, kunamira mataira, sechinhu chakakosha chekubatanidza mataira, kwave kutsiva dhaka resimende rechinyakare zvishoma nezvishoma. Rinoshandiswa zvakanyanya nekuda kwekushandiswa kwaro nyore, kunamira kwakasimba, uye kugara kwenguva refu kwakanaka. Zvisinei, kushanda kwenamira mataira emhando yepamusoro kunoenderana nekugadzirwa kwakakodzera kwezvinowedzera.Hydroxypropyl methylcellulose (HPMC), sechinhu chikuru chinowedzera, ine basa risingatsiviwi.
1. Zvinodiwa pakushanda kweTile Adhesive kune Zvekuwedzera
Zvinodiwa zvikuru pakunamira mataira kusimba kwezvisungo, kushanda zvakanaka, uye kugara kwenguva refu. Mamiriro akasiyana ekuvaka, akadai sekushandiswa kwemadziro nepasi mukati nekunze, uye kugadzira matombo, ane zvinodiwa zvakasiyana-siyana zvekushanda zvakanaka kwekunamira mataira, asi zvinodiwa zvinotevera zvinowanzo shanda:
1.1. Kushandiswa Kwakanaka uye Zviri Nyore Kushandisa
Zvinonamira zvemataira zvinoda kuenderana kuri pakati nepakati kuti zvive nyore kushandisa pasina kutsvedza kana kuyerera zvakanyanya.
1.2. Nguva Yakarebeswa Yekuvhura
Munguva yekuisa mataira, zvinonamira mataira zvinoda nguva yakati kuti zvigadziriswe, saka zvinofanira kuchengetedza hunyoro kudzivirira kuoma nguva isati yakwana.
1.3. Kuchengeta Mvura Kwakanaka Uye Hunhu Hwakanaka Hwekudzivirira Kudonha Kwemvura
Panguva yekuisa madziro, chinamira chemataira chinofanira kugara chakanyorova zvakakwana kuitira kuti mvura irambe yakachena pakati pemataira nepasi pevhu uye kudzivirira mataira kuti asatsvedzerere.
1.4. Kuramba Mamiriro Ekunze Uye Kugara Kwenguva Refu
Munguva yekushandiswa kwenguva refu, chinamira chemataira chinofanira kutsungirira kupisa, kushanduka kwehunyoro, uye kushushikana kwekunze kuitira kuti simba rekubatanidza rirambe rakasimba.
2. Basa Guru reHPMC muTile Adhesive
HPMC (Hydroxypropyl Methyl Cellulose) imhando ye non-ionic cellulose ether inoshandiswa zvakanyanya mu dry-mix mortar formulations nekuda kwekunyunguduka kwayo kwakanaka, kugadzikana kwemakemikari, uye hushamwari hwezvakatipoteredza. Mukunamira mataira, HPMC inonyanya kuita mabasa anotevera:
2.1. Kuchengetwa kwemvura kwavandudzika zvikuru
HPMC inogadzira network yakakora yemamorekuru mumota, ichinyatsovhara hunyoro uye ichinonotsa kunyorova kwesimende, nokudaro ichiwedzera nguva yekuvhurwa kwenamira yemataira uye ichirerutsira kushandiswa kwayo.
2.2. Kuvandudzwa kweMashandiro uye Thixotropy
Kuwedzerwa kweHPMC kunovandudza zvikuru kunyorova uye kunyorova kwetiles, zvichiita kuti zvinyatsoshandiswa zvakanaka uye zvakaenzana. Zvinopawo thixotropy yakanaka, zvichireva kuti kunyorova kwakanyanya kana wakamira wakamira, zvichidzivirira kutsvedza; uye kuwedzera kunyorova kana wakurunga kana waiswa, zvichiita kuti zvive nyore kushandisa.
2.3. Kunamira Kwakawedzerwa uye Hunhu Husingatsvedzeri
HPMC inovandudza simba rekubatana pakati pechinamira chetaira ne substrate nekumashure kwetaira, zvichideredza njodzi yekudonha negomba. Kubatsira uku kunonyanya kuoneka mukuisa mataira makuru.
2.4. Kuramba Kunonaka Kwekutsemuka Uye Kugara Kwenguva Refu
Nekuvandudza kufanana uye hunhu hwekuoma kwedhaka, HPMC inogona kuderedza matombo anokonzerwa nekumanikidzwa kwakanyanya uye kuwedzera hupenyu hwebasa redhaka rinonamira.
3. Maitiro Ekusarudza Chinhu Chinowedzerwa cheHPMC Chakakodzera
Kunyangwe HPMC ichikosha zvikuru mumatira ekunamira mataira, mashandiro ayo anosiyana zvichienderana nematanho akadai sedanho rekutsiva, viscosity, saizi yezvidimbu, uye kupararira. Zvinhu zvinotevera zvinofanirwa kutariswa pakusarudza:
3.1. Giredhi reViscosity
Kusviba kwakanyanya kunovandudza kuchengetwa kwemvura, asi kunogona kuderedza kuyerera kwemvura panguva yekuisa. Zvigadzirwa zvisina kusviba zvakanyanya zviri nyore kuisa, asi zvinogona kukanganisa kuchengetwa kwemvura uye kusatsvedza. Saka, sarudzo yakakodzera inofanira kuitwa zvichienderana nezvinodiwa nemataira uye mamiriro ekushandisa.
3.2. Dhigirii rekutsiva uye rekunyungudika
HPMC yakatsiviwa zvakanyanya inonyungudika nekukurumidza, zvichiita kuti kupararira kuri nani musystem yekunamira mataira, zvichivandudza kugadzikana uye kushanda kwakasimba.
3.3. Magiredhi Ehunyanzvi
Magiredhi eHPMC akasarudzika anowanikwa pamusika, achipa hunhu hwakanaka husingatsvedzeri uye nguva yakareba yekuvhura, zvichiita kuti zvive zvakakodzera kune mataira makuru uye madziro ekunze.
3.4. Kudzivirirwa uye Kuchengetedzwa Kwezvakatipoteredza
Yemhando yepamusoroHPMCinofanira kuzadzisa zvinodiwa zvakatipoteredza, isave ine chepfu uye isingakuvadzi, uye ive nechokwadi chekuti nharaunda yekuvaka yakachengeteka uye yekugara yakachengeteka.
Hunhu hwematira emataira hahuna kungoenderana nehunhu hwesimende nemaaggregates chete, asiwo nekugadzirwa kwesainzi kwezvinowedzera. HPMC, nekuda kwemigumisiro yayo yakabatana yekuchengetedza mvura, kukora, kushanda zviri nani, uye kunamira kwakawedzerwa, chinhu chakakosha mumatira emataira. Kusarudzwa kwakakodzera uye kushandiswa kweHPMC hakungobatsiri chete zvakanyanya kuvandudza mashandiro ekunamira mataira, asiwo kunoderedza njodzi dzekuvaka uye kunovimbisa hunhu hwechivakwa. Kumakambani ekuvaka nemakambani ekuvaka, kugona kusarudza nekushandisa matekiniki eHPMC kwakakosha pakugadzira zvigadzirwa zvekunamira mataira zvemhando yepamusoro.
