Makina a zochita za mphira wa mphira mu matope

Kubwezeretsedwanso ndi ufa wa mochedwa ndi simenti (monga sime, masitepe, dongo, ndi zina zowonjezera, etc. kusakaniza matope. Pamene matope a ufa amawonjezeredwa kumadzi ndikusunthidwa, pansi pa zochita za hydrophilic zoteteza, zomwe zimakhala zokwanira kupanga ufa wokwezedwa mufilimu. Kuphatikizika kwa ufa wa mphira umakhala ndi zotsatira zosiyanasiyana za matope ndi zomangamanga: Kugawana kwa mpweya wa parabani ndi zowonjezera zomwe zimapangitsa kuti mitundu yosiyanasiyana ya matelex ikhale yowonjezera madzi ambiri thixotropy, ndikuwonjezera mamasukidwe.

Nthawi zambiri amakhulupirira kuti makina obwezeretsedwa aposachedwa kuti athandize kugwiritsidwa ntchito kwa matope mwatsopano ndikuwongolera ufa wa matope pomwe amatulutsa matope a matope onga omanga. Matope osakanikirana omwe ali ndi mwayi wopezeka wa latedx ufa wopangidwa, ndikuyamwa madzi pamtunda, mapangidwe ake pang'onopang'ono, madziwo adzacheperana wina ndi mnzake, ndipo pamapeto pake kuphatikizirana. Njira ya mafayilo a polymer imagawidwa magawo atatu. Mu gawo loyamba, tinthu tating'onoting'ono timasunthira momasuka mu mawonekedwe a brownian kuyenda koyambirira. Madzi amatuluka, kusuntha kwa tinthuko kumakhala kokha komanso kokha kwambiri, komanso zovuta zam'madzi pakati pa madzi ndi mpweya zimawakakamiza kuti azitsatira pang'onopang'ono. Mu gawo lachiwiri, tinthu tating'onoting'ono titakumana ndi wina ndi mnzake, madzi omwe ali pamagulu ang'onoang'ono amatuluka pamtunda wa tinthu tating'onoting'ono toyambitsa matenda. Gawo lachitatu ndi lotsiriza limalola kutsutsana (nthawi zina kumatchedwa kuti kudzitsatira) kwa mamolekyulu a polymer kuti apange filimu yopitilira yopitilira. Mukamapanga makanema, tinthu tating'onoting'ono tating'ono tinthu tating'onoting'ono timene tinthu tating'onoting'ono tambiri ndi gawo latsopano ndi nkhawa yayikulu. Mwachidziwikire, kuti athetse ufa wobwezeretsera polima kuti apange filimu mu matope owuma, ndikofunikira kuonetsetsa kuti kutentha kochepa kumapangitsa kutentha kochepa (Mft) ndikotsika kuposa kutentha kwa matope.

Ma Colloids ayenera kulekanitsidwa ndi dongosolo la ma polimanemer. Uwu si vuto mu matope a alkaline a alkaline a alkaline, chifukwa lidzawonongedwa ndi alkali opangidwa ndi simenti ya Quartz pang'onopang'ono mikhalidwe.

Ndi mapangidwe omaliza a filimuyo, njira yopangidwa ndi zopangira zonunkhira komanso zowoneka bwino zimapangidwa mu matope obisika, ndiye kuti mafupa olimba ndi opanda phokoso opangidwa ndi ufa wa mopukutira. network yosinthika. Mphamvu yamphamvu ndi coutheon of the Polymer ficn yopangidwa ndi ufa wa latx imakulitsidwa. Chifukwa cha kusinthasintha kwa polymer, kuthekera kokulirapo ndikokwera kwambiri kuposa mawonekedwe a miyala yamiyala, ndikupangitsa kuti kufafaniza kupsinjika kumayenda bwino, potero kumathandizira kukana kwa matope.

Ndi kuwonjezeka kwa zomwe zili mu ufa waposachedwa, dongosolo lonse limayamba kulowera pulasitiki. Pankhani ya ufa wambiri wa matope, gawo la polymer mu matonthoti lomwe limachirikiza limapitilira gawo la mankhwala opangira zipatso, ndipo matonthowo asintha ndikusintha, pomwe kuphatikizika kwa simenti kumakhala "filler". . kuphatikizika kwa matope. Kudzera mwamphamvu zamkati, matope amasungidwa mokwanira, ndikuwonjezera mphamvu ya matope. Kukula. Kuphatikiza apo, maofesi a polymer ophatikizika amalepheretsanso ma coialesracks mu ming'alu yolowera. Chifukwa chake, ufa wobwezeretsedwa umapangitsa kuti nkhawa ikhale ndi nkhawa komanso kulephera kwa zinthuzo.

Kanema wa Polymer mu matope osinthika ali ndi zotsatira zofunika kwambiri pakulimbana ndi matope. Ufa wokwezedwa walandu wogawika pamtunda umagwiranso ntchito ina yofunika kwambiri atamwazikana ndikupanga mafilimu, omwe ndikuwonjezera chotsatsa kwa zida zolumikizana. Mu micrestructuction wa polymer kusinthidwa kwa matope okhala ndi mawonekedwe a matope ndi tiles, kanema wopangidwa ndi polymer amapanga matope ocheperako komanso matope a simenti. Malo olumikizirana pakati pa zinthu ziwiri zopanda chinyengo ndi malo owopsa chifukwa cha ming'alu yovuta kuti apange ndikupangitsa kuti athetse coutheon. Chifukwa chake, kuthekera kwa mafilimu a Lasanx kuti muchiritse ming'alu yovuta ndikofunikira kwambiri kwa ma tiles.
