Zinthu Zomwe Zimakhudza Mphamvu Zomangira Zomatira

Zinthu Zomwe Zimakhudza Mphamvu Zomangira Zomatira

1. pamwamba roughening

Zomatira zikamafalikira pamwamba pa zinthuzo, kuwungutsa pamwamba kumathandizira kufalikira kwa zomatira ndikuwonjezera kuchuluka kwa malo olumikizana pakati pa zomatira ndi zinthuzo, izi zidzakulitsa mphamvu yomangirira. M'malo mwake, ngati zomatirazo zikulephera kufalitsa bwino zinthuzo, kuwombana kwapamwamba kudzachepetsa mphamvu yomangirira.

2. Chithandizo chapamwamba

Kukonzekera pamwamba musanayambe kugwirizana ndi chinsinsi cha mgwirizano wopambana. Cholinga chake ndi kukwaniritsa zolumikizana zolimba komanso zolimba. Chifukwa cha kukhalapo kwa magawo ofooka a malire opangidwa ndi oxide layers monga dzimbiri, chrome plating layers, phosphating layers, zotulutsa, ndi zina zotero. pa zomangira, chithandizo chapamwamba cha adherent chidzakhudza mphamvu yomangira. Mwachitsanzo, malo a polyethylene amatha kuthandizidwa ndi okosijeni otentha a chromic acid kuti apititse patsogolo kulumikizana.

3. Lowetsani

Pambuyo polumikizana, chophatikiziracho nthawi zambiri chimakhudzidwa ndi chilengedwe, mamolekyu ang'onoang'ono ngati madzi kapena zosungunulira zimatha kulowa mu guluu wosanjikiza. Mwachitsanzo, pakanyowa kapena pansi pa madzi, mamolekyu amadzi amalowa mu guluu; mu zosungunulira organic, zosungunulira mamolekyu amachita chimodzimodzi. Mamolekyuwa amayamba amapangitsa guluu kusintha mawonekedwe ake, kenako nkufika polumikizana ndi guluu ndi pamwamba. Izi zidzafooketsa mgwirizano, ndipo pamapeto pake zidzalephera. Kulowa sikungoyambira m'mphepete mwa guluu wosanjikiza. Ngati chomangiriracho chili ndi porous, mamolekyu ang'onoang'ono amatha kulowanso kudzera mu mipata, pores, kapena ming'alu yake, kenako ndikufika polumikizira ndikuchepetsa mphamvu yolumikizana. Kulowa kumeneku sikungochepetsa mphamvu ya thupi la mgwirizano koma kungayambitsenso kusintha kwa mankhwala pa mawonekedwe, monga dzimbiri, zomwe zimapangitsa kuti mgwirizanowo ukhale wopanda ntchito.

4. Kuyenda

Zida zomangika zimakhala ndi mapulasitiki, monga PVC. Popeza kuti mamolekyu ang'onoang'onowa sasakanikirana bwino ndi ma polima, amachoka mosavuta kuchoka pamwamba pa zinthuzo kapena polumikizana. Ngati tinthu tating'ono tating'ono tating'ono tasamuka tikhala pamodzi pa mawonekedwe, amalepheretsa zomatira kuti zisamamatire ku zinthu, kupangitsa kuti chomangiracho chilephereke.

5. Kupanikizika

Mukamamatira, kanikizani kukakamiza pamwamba. Izi zimathandiza guluu kudzaza mabowo ang'onoang'ono pazinthuzo mosavuta, ngakhale mabowo akuya ndi machubu ang'onoang'ono, ndikuchepetsa zomata zoyipa. Pa zomatira zofooka, kukanikiza kumawapangitsa kuti aziyenda kwambiri ndikusiya guluu wokwanira. Chifukwa chake dikirani mpaka guluu likhale lolimba kwambiri polumikizana musanakanize. Izi zimakankhiranso mpweya kuchokera pamwamba pa zinthuzo ndipo zimachepetsa thovu la mpweya pamalo omatira. Kwa zomatira wandiweyani kapena olimba, kukanikiza ndikofunikira mukamatira. Muzochitika izi, nthawi zambiri mumafunika kuzitenthetsa bwino kuti zikhale zowonda kapena kutembenuza madzi. Mwachitsanzo, kupanga insulating pressing layer kumachitika pansi pa kutentha ndi kupanikizika. Kuti mupeze mgwirizano wamphamvu, gwiritsani ntchito kukakamiza kosiyanasiyana kwa zomatira zosiyanasiyana. Ndipo nthawi zambiri, gwiritsani ntchito kukakamiza kwakukulu kwa zomatira zolimba kapena zokhuthala, komanso kutsika kwa zomatira zoonda.

6. Makulidwe a guluu wosanjikiza

Zomatira zokhuthala zimapeza mosavuta thovu la mpweya, zolakwika ndi kusweka koyambirira, chifukwa chake muyenera kupanga guluu kukhala woonda momwe mungathere kuti mugwirizane kwambiri. Komanso, magulu a guluu akatenthedwa, kukulitsa kwawo kumapangitsa kuti pakhale kutentha kwambiri m'malo olowa, zomwe zimapangitsa kuti olowa aduke mosavuta. Zopanikizika pamagulu enieni ndizovuta, kuphatikizapo kumeta ubweya, kupsinjika kwa peel ndi kupsinjika mobwerezabwereza. Choyamba, kumeta ubweya wa tsitsi: pamene kuchoka - mphamvu yokoka pakati ikugwiritsidwa ntchito, kupsinjika kumamangirira kumapeto kwa mgwirizano. Kupatula kumeta ubweya wa ubweya, palinso mphamvu yokoka molumikizana ndi olowa ndi kung'ambika pagululo. Pamene mfundoyo ikumeta ubweya wa thonje, mfundoyo ikakhala yokhuthala, m'pamenenso mfundoyo imakhala yolimba. Chachiwiri, kupsinjika kwa peel: izi zimachitika zinthu zomwe zimamatidwa ndi zofewa. Mphamvu zonse zokoka komanso zometa ubweya zimagwira ntchito pamgwirizanowu, ndipo mphamvu zonse zimakhazikika pagululi - zinthu zakuthupi, kotero olowa amathyoka mosavuta. Chifukwa kupsinjika kwa peel kumawononga kwambiri, muyenera kupewa mapangidwe omwe amapangidwa popanga. Chachitatu, kupsinjika kobwerezabwereza: guluu womwe uli mgululi umatha pang'onopang'ono chifukwa cha kupsinjika kobwerezabwereza ndikusweka pang'onopang'ono kuposa kupsinjika kwanthawi zonse. Zomatira zolimba komanso zotambasuka, monga zomatira, zimatha kupsinjika mobwerezabwereza.

7. Kupsinjika kwamkati
   Choyamba, kupsinjika kwa shrinkage: Guluu akachiritsa, amachepa kwambiri chifukwa cha nthunzi, kuziziritsa komanso kusintha kwamankhwala, zomwe zimayambitsa kupsinjika. Pamene mphamvu yochepetsera imakhala yamphamvu kuposa mphamvu yomatira, mphamvu yowoneka bwino ya mgwirizano idzatsika kwambiri. Komanso, kugawanika kosagwirizana kozungulira kuzungulira m'mphepete mwa ma bond kapena mipata mu guluu kumayambitsa kupsinjika, zomwe zimawonjezera mwayi wopanga ming'alu. Zomatira za crystalline zimachepa kwambiri akachira chifukwa cha kupangika kwa kristalo, zomwe zimapangitsanso kupsinjika kwa mkati mwa olowa. Ngati muwonjezera kuchuluka kwa zida za raba zomwe zimatha kuwunikira kapena kusintha kukula kwa kristalo, mutha kuchepetsa kupsinjika kwamkati. Kuonjezera zolimbitsa thupi ku zomatira za thermosetting resin ndiye chitsanzo chabwino kwambiri. Mwachitsanzo, pa phenolic-acetal glues, pamene acetal zili pansi pa 40%, olowa amangokhala kulephera kwa mawonekedwe; pamene ili pamwamba pa 40%, imakhala ndi kulephera kogwirizana, ndipo mphamvu ya mgwirizano imawonjezeka kwambiri. Chachiwiri, kupsinjika kwa kutentha: Utomoni wosungunuka ukazizira ndi kuchira chifukwa cha kutentha kwambiri, umachepa kwambiri. Chomangiracho chimachigwira, chomwe chimapangitsa kuti pakhale kupanikizika kwapakati pa mawonekedwe. Ngati maunyolo a maselo amatha kudutsana, kupsinjika kwamkati kumatha. Zinthu zazikulu zomwe zimakhudza kupsinjika kwa kutentha ndizowonjezera kutentha kwa kutentha, kutentha kwa chipinda, kusiyana kwa kutentha ndi kusiyana kwa kuuma. Kuti muchepetse kupsinjika kwa kutentha komwe kumabwera chifukwa cha mitundu yosiyanasiyana ya matenthedwe, muyenera kupanga kuchuluka kwamafuta a guluu pafupi ndi zomwe zikumatiridwa. Kuonjezera zodzaza ndi njira yabwino - mutha kuwonjezera ufa wazinthu zomwezo, kapena ulusi ndi ufa wazinthu zina.
