Zilembo zamphepete mwa mchenga wa polymer

Kusankha mfundo zogwiritsa ntchito njira za m'munda komanso malo ammudzi, musamaganizire zowonongeka zokha, komanso kuti mutha kukwanitsa.

Matalala akhoza kukhala ndi mawonekedwe osiyana, makulidwe, mitundu, makulidwe ndi zomangamanga, koma ayenera kukhala ndi mphamvu zamphamvu ndi kukana zochitika zaukali zakunja. Zinthu zoterezi zimadziwika ndi zamakono zowonjezera mchenga. Nkhaniyi ndi yatsopano, koma yayamba kale kudziwonetsera bwino.

Makina opanga makina komanso kusankha zipangizo

Maonekedwe a mchenga wa polima amapanga zigawo zitatu zokha:

• Mchenga (pafupifupi 75%);
• Kuthamanga kwambiri kwa propylene kapena propylene;
• Diso la chiyambi.

Maonekedwe ndi mphamvu za zinthuzo zimadalira mtundu wa zipangizo zomwe amagwiritsa ntchito. Pogwiritsa ntchito makinawa, chidwi chenicheni chimaperekedwa makamaka ku mchenga wabwino. Musanagwiritse ntchito, ndi bwino kutsukidwa, sieved ndi calcined pa kutentha. Kukula kwa particles ndikofunikira kwambiri, choncho, mchenga wausinkhu waukulu umawasankha.

Pambuyo posakaniza zokhazokha zonse kuti zikhale zofanana ndi maonekedwe ndi mtundu, chisakanizocho chimatumizidwa ku malo enaake osakanikirana, komwe kamasakanikirana ndi kusungunuka. Kenaka chisakanizocho chimatumizidwa pansi pa makina osindikizira ndi mbale za zofunidwa kukula ndi mawonekedwe amapangidwa kuchokera pamenepo.

Tile yoteroyo imatha kupirira kutentha kufika mpaka -70 ° C pamene siimasokoneza ndipo siifala mosiyana ndi mchenga wa polymer konkire pamatumba.

Makhalidwe ndi katundu wa zinthuzo

Zilembo zamphepete mwa mchenga wa polymer zili ndi zotsatirazi ndi ubwino:

• msinkhu wa kuvala kukana ndi mphamvu;
• kusakaniza kwa madzi (chinyezi sichilowa mkati, koma chimadza pamtunda ngati mawonekedwe);
• kukana mankhwala osokoneza bongo;
• kulemera kwake;
• kulimbana kutentha kwakukulu;
• chisangalalo cha kukhazikitsa;
• zosiyana, mawonekedwe ndi mitundu ya tizigawo ting'onoting'ono.

Koma ziyenera kukumbukiridwa kuti mfundozi zikhoza kukulirakulira chifukwa cha kutentha, kotero kuika mchenga wamadzimadzi amadzimadzi kumapanga zofunikira.

Zinsinsi za kuika

Makhalidwe a mchenga wa polymer amalola kuti agwiritse ntchito ponseponse m'mizinda komanso pokonza malo a chilimwe. Ntchito yokonzekera imayamba ndi maziko omwe zipangizo zamakono zidzadalira. Ikhoza kukhala ya mitundu iwiri: mchenga kapena miyala.

Kuyika pa maziko a mchenga kumachitidwa mwanjira yomweyo.

1. Kuchokera kumalo kumene miyalayi idzayikidwa, dera lakumtunda (15-20 cm) lichotsedwa.
2. Kenaka mazikowo amamangidwanso ndipo amawongolera pamtunda.
3. Pamphepete mwace mumapangidwira mchenga wapadera, womwe umadzutsa mchenga mumtunda wa 5cm, madzi otsekedwa komanso amathamanga.
4. Kulemba kansalu kumachitika, kenako kuika miyala yokhota kumatsatira.
5. Mndandanda wa geotextile wokhala ndi 15-20 masentimita umakhala pamwamba pa nthaka yokonzedwa.
6. Kuchokera pamwamba, pamtunda wa geotextile, mchenga umatsanuliridwa, ndiye umakhetsedwa ndi madzi, ophatikizidwa ndi opangidwa. Pali zigawo zingapo za mtundu uwu.
7. Komanso, matayalawo amaikidwa ndi mpata wa 3-5 mm ndipo amagwiritsidwa ntchito pogwiritsa ntchito nyundo yampira.
8. Mabalawo amadzaza ndi mchenga atagona.

Kuyika pa maziko a miyala kumaphatikizapo kukhazikitsidwa kwa mfundo 4 zoyambirira, ndiyeno dera ladzaza ndi miyala yophwanyika ndi yofanana. Mwala wosweka umatsanulira ndi konkire screed pa masentimita 5-10. Matabwawa amaikidwa padera wapadera kapena konki osakaniza (2-3 masentimita wosanjikizika), mcherewo umadzaza ndi mchenga kapena youma osakaniza a konkire ndi mchenga. Mukatha kuyanika, ayenera kupukutidwa ndi burashi yolimba.
