Zomatira polypropylene ndi polyethylene

Polypropylene ndi polyethylene ndi zipangizo, amene ali ovuta kwambiri kupereka kogwirizana. Ngati mulibe ntchito kuwotcherera, ndondomeko kulumikiza zinthu awiri adzakhala mabvuto. Mwa zina, ndi pamalo muyenera provisional kukonzekera koyamba. zomatira mwina ntchito polypropylene Kapenanso.

The mitundu yaikulu ya zomatira

Ngati mukufuna zomatira kwa pulasitiki, muyenera kudziwa kuti izo zifika ku oonetsera awiri: thermoset ndi thermoplastic zikuchokera. Monga maziko a woyamba kuchita epoxy, ndi poliyesitala thermoset utomoni. Gulu lachiwiri la zomatira akhoza kugawidwa mu magulu awiri, woyamba anapangidwa pamaziko a labala, pamene lachiwiri - pamaziko a resins.

Nyimbo Thermoplastic iodzafewa ndipo kupasuka zipangizo mchikakamizo cha kutentha. Ngati kuyerekeza ndi thermosetting, iwo sasintha dongosolo mankhwala awo pa mgwirizano, umene uli mwayi kwambiri. Zomatira polypropylene akhoza kugawidwa ngakhale ndi chiwerengero cha zigawo zosakaniza amenewa mono- kapena bicomponent. Choyamba kuperekedwa monga chotsirizidwa mu phukusi wina. Zikuphatikizapo zomatira "kamphindi" chifukwa polypropylene. A yachiwiri mmatumba mu phukusi awiri omwe anali ndi zosakaniza kusakaniza. Mwachitsanzo, taganizirani imodzi chigawo zikuchokera mungathe Cosmoplast 500 ponena kulumikiza Mbiri mu kupanga zenera. Ngati mukufuna ziwiri zikuluzikulu, n'zotheka ntchito ndi epoxy zomatira kwa pulasitiki, womwe wapangidwa pamaziko a wothandizila akuchiritsa ndi epoxy utomoni. Ziwiri zikuluzikulu zomatira ali ndi mwayi, amene yafotokozedwera yosungirako yaitali. Chifukwa chake n'chakuti zosakaniza musati amakhudzana ndi akuchiritsa sadzafika pamaso kulumikiza.

Tatchulawa zomatira polypropylene amachita ngati zikuchokera chimodzi chigawo amene angagwiritsidwe ntchito mu mafakitale ndi tsiku. Thiabendazole angagwiritsidwe ntchito kugwirizana kogwirizana pa makona a ° 45. osakaniza kuposa anzawo mu wamfupi kuyanika nthawi. The zikuchokera kugonjetsedwa ndi madzi kutentha ndi kuzizira. Kuyandikira kuyanika ake nthawi masekondi 3, ndi pa akuchiritsa komaliza pa 20 ° C ndi maola 16.

Opaleshoni Malangizo 500 Cosmoplast

Ngati mukufuna kugwiritsa ntchito pamwambapa anafotokoza zomatira kwa polypropylene, ayenera choyamba bwino ntchito yake. Ikani osakaniza ayenera kukhala likusonyeza chidebe kapena pamodzi ndi Cosmoplast parser njira zomwe ndi chipangizo metering. ntchito ayenera kuchitidwa pa mbali pamwamba, amene kale zofunika kuyeretsa kuchokera ku dothi ndi fumbi, ndi zouma. Kukonza tingachite ndi thandizo la zipangizo lapadera kwa mtundu wa "Kosmofen 60". The kali kuti chilumikizidwe, pansi kuthamanga kwa nthawi mwachindunji pamaso atayanika kunja. Chifukwa kukhuthala otsika zikuchokera anafotokoza sangaime mavuto angongole kusiyana. Ngati mukufuna kulumikiza mipata yaikulu, zikhoza kugwiritsidwa ntchito pa kuchenjera kwa Cosmoplast 564.

Kukonza zomatira

Zomatira kulumikiza polypropylene akhoza mwayeretsa zina ntchito yokonza nezasohshem "Kosmoplast 597". Kusamba mphamvu volumetric ya zomatira nezasohshego adatengedwa ndi njira yomweyo. Ngati zomatira kale anakwanitsa youma, ndiye inu mukhoza kukonzamo ndi dzanja. Pamene pamalo amapanga zosungunulira, zomatira akhoza utauma kwathunthu kuchotsedwa.

Zochita za masitampu sealant-zomatira Dow Corning 7091

Izi zomatira-sealant kwa polypropylene ndi viscous madzimadzi misa ponena kuti asindikize zimfundo ndi kuteteza pamalo osiyanasiyana. The zikuchokera angagwiritsidwe ntchito zipangizo kogwirizana homogeneous ndi mzake. Mwa makhalidwe waukulu zomatira akhoza kuwasiyanitsa, motere:

• luso kusindikiza ndi kumata zosiyanasiyana;
• kutenthetsa kukana;
• kukana kuti cheza ultraviolet;
• durability;
• Mkulu guluu wolimba zipangizo zosiyanasiyana;
• mkulu elasticity wa msoko lapansi.

Tiyenera kukumbukira kuti sealant mwina yodziwika ndi mtundu asidi akuchiritsa, amasonyeza kuti zikuchokera ali ndi luso kuonetsetsa wina kuchuluka kwa asidi acetic pa solidification. Zimenezi zingachititse chiwonongeko zitsulo sanali akakhala ndi dzimbiri awo. Izi ziyenera mulinso mabo ndipo ena zipangizo zina. zomatira Ichi ndi chonse, ndi yabwino ndi yosavuta kugwiritsa ntchito, ali ndi makhalidwe a kukana madzi ndi kukana mankhwala ndi kugwedera. Iwo akhoza opareshoni pa kutentha kwa -55 kuti +180 ° C. Izi mankhwala zomatira ndi polypropylene mandala firiji, izo ziyenera guluu wolimba popanda priming zina ndi zipangizo ochiritsira. The zikuchokera watha kuchita ntchito ya zomatira wosanjikiza makulidwe a 5 mm, zikhoza kugwiritsidwa ntchito ngati sealant, ngati wosanjikiza kupanga mpaka 25 mm. Pamene ntchito amaimira inductile pasty kugwirizana. Nditamaliza sitepe kuumitsa kugwirizana akufanana mphira zotanuka. Khalidwe zofunika kuonetsetsa ndi sealability zipangizo homogeneous ndi anthu amene ali osiyana matenthedwe kuwonjezeka koyefishienti.

Chifukwa kusankha sealant mtundu Dow Corning 7091

Pamwambapa anafotokoza zomatira kwa polypropylene ndi polyethylene ali ndi makhalidwe mafuta kukana, kukana kwa chinyezi, elasticity mkulu ndi mphamvu. N'zosavuta ntchito Inter zina zotere, ndi waluso mwa likufa kutentha kwa -55 kuti +180 ° C.

Features ya ntchito

The pamalo wosindikiza ayenera degreased, kutsukidwa ndi zouma. Degreasing ndi solvents mwina mtundu wa acetone kapena mowa isopropyl. Chofunika kuchuluka kwa sealant iyenera kugwiritsidwa ntchito pamwamba chimodzi, kenako kugwirizana zapansi awiri. Sinthani dongosolo tonse zigawo zikuluzikulu kungakhale mu mphindi 15 pambuyo ntchito mpaka filimu aumbike padziko zomatira. Ngati zinthu zimapezeka kwa firiji ndi chinyezi wachibale 50%, akuchiritsa liwiro adzakhala wofanana mamita 2 pa tsiku. Ngati zili chinyezi yafupika, ndi solidification nthawi kwambiri.

Makhalidwe WEICON Easy-Mix Pe-PP bicomponent zomatira

Mapangidwe awa ndi ziwiri zikuluzikulu kusakaniza kulumikiza polyethylene ndi polypropylene. Linapangidwa pamaziko a acrylate, ndipo ali mkulu zomatira mphamvu ya mapulasitiki otsika mphamvu ndi mapulasitiki. N'zochititsa chidwi kuti pretreated pamwamba Sikuti. zikuchokera Izi zosunthika, choncho angagwiritsidwe ntchito kulumikiza wa polyamide ndi, polyvinyl enaake, polycarbonate, polymethyl methacrylate, komanso fiberglass ndi zipangizo zina.

Pomaliza

Ntchito imodzi mwa nyimbo pamwamba mukufuna kumata ndi machubu polypropylene, kutentha kwa chipinda ayenera kukhala mu osiyanasiyana kuchokera +5 kuti +35 ° C. Kukhala ndi zomatira mfuti, burashi ndi bristles zachilengedwe, komanso chitoliro wodula. Patsogolo ntchito zomatira m'mphepete zigawo ayenera ankawachotsera kunja, njira yokha adzatha kupeza mkulu kudalirika msoko.
