Polymer kankare: abun da ke ciki, iri, halaye, da aikace-aikace da kuma fasahar da sake dubawa

Polymer kankare - musamman gini abu, wanda aka yi amfani a matsayin m, kazalika don maye farar ƙasa cements. A wasu lokuta, da polymer da ake amfani da matsayin ban da Portland sumunti. Yana da wani m, m kumshin abu samu ta hanyar hadawa daban-daban ma'adinai fillers da roba ko na halitta astringent jamiái. Wannan ci-gaba injiniya kayan amfani a mutane da yawa masana'antu, amma shi ne ya fi kowa a cikin shiri masana'antu.

iri

A yi amfani da iri uku polymer kankare. Next, mukalli su samar da fasaha, ikon yinsa, da kuma abun da ke ciki to da janar ra'ayin na polymer kankare da su gyare-gyare.

Polymer kankare qagaggun (kankare aka polymer-modified)

Wannan irin kankare sanya daga Portland sumunti abu da modified polymer kamar acrylic, polyvinyl acetate da ethylene roba acetate. Yana da kyau mannewa, high flexural ƙarfi ne, kuma low permeability.

Acrylic polymer modified kankare halin da m launi, wanda aka sa ya ke cikin babban bukatar tsakanin magina da kuma gine-ginen. Its sinadaran gyara ne kama da na al'ada ciminti bambancin. The adadin polymer yawanci jeri daga 10 zuwa 20%. Kankare, modified a cikin wannan hanya yana da ƙananan mataki na permeation da hakan yawa fiye da m ciminti. Duk da haka, ta tsarin mutunci dogara da gaske a kan m na Portland sumunti.

kankare ƙasƙanci iya daukar tsawon rai idan yana da wani high yawa da kuma wani karami surface area. A zumunta kyautata a cikin sinadaran da kwanciyar hankali na polymer-modified abu zuwa Portland sumunti yiwu a wani acidic matsakaici.

Guduro impregnated kankare

A guduro impregnation domin kankare yawanci sanya ta gabatar da wani monomer a low yawa hydrated Portland sumunti, ya bi ta hanyar radiation ko thermal polymerisation kara kuzari. A ire sassauci na da irin wannan kankare ta 50-100% hakan fiye da talakawan.

Duk da haka, da polymer modulus 10% fi ta al'ada kankare. Saboda wadannan kyau kwarai halaye, daga wani jam'i na zabin don amfani mai polymeric yi abu za a iya dabam da aka ambata samar:

• cikas.
• gadoji.
• bututu.
• bene tiles.
• laminate yi.

gabatar da tsari fasahar hada kankare-bushewa cire danshi daga samanta, da yin amfani da monomers a wani bakin ciki Layer da yashi, sa'an nan polymerizing da monomers amfani da wani zafi juyi. Saboda haka, kankare saman da ƙananan ruwa permeability, sha, abrasion juriya da kuma yawanci high ƙarfi. Har ila yau, don inganta lalacewa juriya, da juriya ga sanyi da kuma danshi, ana amfani da polymeric coatings for kankare, bulo, dutse, benaye, da dai sauransu.

Yana yana da kõme ba su yi tare da saba mana to Portland. Kafa ta duwatsu hade tare da wani polymeric m abu wanda ba ya dauke da ruwa. Polystyrene, acrylic da epoxy resins ne monomers wanda ake amfani da ko'ina a cikin yi da irin wannan kankare. Sulfur kuma a matsayin mai polymer. Sulfur kankare da ake amfani da gine-gine bukata high jure acidic yanayin. Thermoplastic polymers amma yawanci thermosetting guduro amfani da matsayin babban guduro bangaren saboda su high thermal zaman lafiya da kuma kwanciyar hankali ga mai fadi da kewayon sunadarai.

Polymeric kankare aka hada da raka'a wanda sun hada da silica, ma'adini, dutse, farar ƙasa da sauran ingancin kayan. Naúrar dole ne na kyau inganci da free daga turɓãya, tarkace da kuma wuce haddi danshi. Rashin bin wadannan sharudda za su iya rage bond ƙarfi tsakanin polymeric m da filler.

Musamman polymer kankare

Modern gini abu daban-daban daga da magabata. Yana yana da wadannan halaye:

• High jure sinadaran da nazarin halittu yanayin.
• Kamar yadda idan aka kwatanta da sumunti-kankare kayayyakin, shi yana kasa taro.
• Daidai garwaya da amo da vibrations.
• Vyvetrivaemost da kyau UV juriya.
• The ruwa sha.
• Yana za a iya yanka ta yin amfani da drills da grinders.
• Yana za a iya aiwatar da shi murƙushe dutse ko dandaƙewa don amfani da hanya tushe.
• Game 4 sau da karfi fiye da ciminti kankare.
• Good rufi dũkiyarsu da kuma kwanciyar hankali.
• Matsananci-gama, wanda facilitates ingantaccen na'ura mai aiki da karfin ruwa ya kwarara.

da yin amfani da

Polymer za a iya amfani da sabon shiri, ko gyara na haihuwa abu. Its m kaddarorin da damar dawo da duka biyu da polymer da kuma al'ada kankare, ciminti-tushe. Low permeability da kuma lalata juriya da damar da amfani a iyo wuraren waha, najasa tsarin, magudanun ruwa tashoshi, electrolytic Kwayoyin da sauran Tsarin dauke da ruwa ko lalatattu sunadarai. Shi ya dace domin gina da kuma gyaran rijiyoyin, saboda da ikon tsayayya da guba da kuma lalatattu lambatu gas da kwayoyin fiye samu a ruwa tsarin.

Ba kamar gargajiya kankare Tsarin, shi ba ya bukatar wani shafi ko waldi seams kare PVC. Za ka iya ganin aikace-aikace na polymer kankare a tituna. Ana amfani da a yi da wani shingen kan hanya, sidewalks, magudanun ruwa ramuka, marẽmari. Har ila yau a titi a polymer shafi for kankare da aka kara wa kwalta a yi na waje yankunan, runways da kuma sauran wurare, wanda aka located in bude iska da kuma ake kaiwa da komowar waje weathering.

reviews

A polymer kankare ba a yadu soma saboda high halin kaka da kuma matsaloli hade tare da gargajiya masana'antu da fasahar. Duk da haka, ci gaban kwanan nan ya jagoranci wani gagarumin raguwa a halin kaka, wanda ke nufin cewa ta yin amfani da an ƙara zama na kowa. Duk da dukan da abũbuwan amfãni a kan al'ada kankare, da ra'ayinta game da boye korau muhalli abubuwan da sau da yawa faruwa saboda rashin masana'antu, da yin amfani da low quality-gyara da kuma take hakkin rabbai.

Har ila yau, fasahar samar da polymer kankare yana mai yawa nuances, kuma asirin da cewa babu wanda ya nẽmi bayyanãwa. Kuma ba shakka, kamar yadda muka gani da sake dubawa, polymer kasuwar farashin ne quite high. Wannan shi ne saboda da wahala da ta samar, da kuma tsada aka gyara, wanda ake amfani da su haifar da shi.
