Ubwino wogwiritsa ntchito HPMC mu zomatira matailosi

1. Kupititsa patsogolo ntchito yomanga

1.1. Limbikitsani magwiridwe antchito

HPMC ili ndi mafuta abwino komanso omatira. Kuyiphatikiza pa zomatira matailosi kumatha kupangitsa kuti matope azigwira bwino ntchito, kupangitsa kuti ikhale yosavuta kukwapula ndi kusalala, komanso kumapangitsa kuti ogwira ntchito yomanga azigwira bwino ntchito komanso amamanga.

 

1.2. Pewani kugwa

Pamene zomatira za matailosi zimagwiritsidwa ntchito pamtunda, zimakhala zosavuta kugwedezeka chifukwa cha kulemera kwake. HPMC bwino bwino odana ndi sagging katundu wa zomatira mwa thickening ndi thixotropic katundu, kuti matailosi kukhalabe khola udindo pambuyo paving ndi kupewa slippage.

 

2. Limbikitsani kusunga madzi

2.1. Chepetsani kutaya madzi

HPMC ili ndi ntchito yabwino yosungira madzi. Zitha kuchepetsa kwambiri kutuluka kwamadzi mwachangu kapena kuyamwa ndi gawo loyambira mu zomatira matayala, mogwira mtima kutalikitsa nthawi yotseguka ndi nthawi yosinthira zomatira, ndikupatsa ogwira ntchito yomanga kusinthasintha kwakukulu kogwira ntchito.

 

2.2. Limbikitsani simenti hydration reaction

Kusungidwa bwino kwa madzi kumathandizira simenti kuti ikhale ndi madzi okwanira komanso kupanga zinthu zambiri za hydration, potero kumawonjezera mphamvu yomangirira komanso kulimba kwa zomatira matailosi.

 

3. Kupititsa patsogolo mgwirizano ndi mphamvu

3.1. Sinthani mawonekedwe olumikizana nawo

HPMC imapanga mawonekedwe abwino a polymer network mu zomatira, zomwe zimakulitsa kulumikizana pakati pa zomatira matailosi ndi matailosi ndi gawo loyambira. Kaya ndi matailosi oyamwa kapena matailosi okhala ndi madzi otsika (monga matailosi opangidwa ndi vitrified ndi matailosi opukutidwa), HPMC ikhoza kupereka mphamvu yolumikizana yokhazikika.

 

3.2. Limbikitsani kukana kwa crack ndi kusinthasintha

Mapangidwe a polima a HPMC amapangitsa zomatira za matailosi kukhala ndi kusinthasintha kwina, komwe kumatha kusinthasintha pang'ono kapena kukulitsa kutentha ndi kutsika kwa gawo loyambira, ndikuchepetsa zovuta zamakhalidwe monga kung'ambika ndi kusweka chifukwa cha kupsinjika maganizo.

 

4. Kupititsa patsogolo luso la zomangamanga

4.1. Sinthani kumadera osiyanasiyana omanga

Pansi pa nyengo yovuta monga kutentha kwambiri, kuuma kapena mphepo yamphamvu, zomatira wamba za matailosi zimauma mwachangu, zomwe zimapangitsa kuti mgwirizano ukhale wolephera. HPMC imatha kuchedwetsa kutayika kwa madzi chifukwa chosunga bwino madzi komanso kupanga mafilimu, kupangitsa zomatira zamatayilo kuti zigwirizane ndi zomangamanga m'malo osiyanasiyana.

 

4.2. Amagwiritsidwa ntchito ku magawo osiyanasiyana

Kaya ndi wosanjikiza matope a simenti, slab wa konkire, matailosi akale kapena gawo lapansi la gypsum, zomatira za matailosi okhala ndi HPMC zowonjezeredwa zimatha kupereka magwiridwe antchito odalirika, kukulitsa mawonekedwe ake.

 

5. Kuteteza chilengedwe ndi chitetezo

HPMC ndi zinthu zobiriwira komanso zachilengedwe zomwe sizowopsa, zopanda fungo, zosayaka, ndipo sizingawononge chilengedwe kapena thanzi la anthu. Sichimamasula zinthu zovulaza panthawi yomanga, zomwe zimagwirizana ndi lingaliro lachitukuko la nyumba zamakono zobiriwira.

 

6. Kuchita bwino kwachuma komanso kwanthawi yayitali

Ngakhale mtengo wa HPMC ndi wokwera pang'ono kuposa zowonjezera zachikhalidwe, zimathandizira kwambiri magwiridwe antchito a zomatira matailosi, zimachepetsa kukonzanso ndikuwonongeka kwa zinthu, ndipo zimakhala ndi phindu lalikulu kwambiri pazachuma pakapita nthawi. Zomata za matailosi apamwamba kwambiri zimatanthawuza kusamalidwa bwino, moyo wautali wautumiki komanso zomangira zabwinoko.
