Kodi kusankha guluu polyethylene: malangizo ndi ndemanga

Polyethylene - wina zipangizo wotchuka kwambiri ndi odziwika. Osakwera mtengo kwambiri ndipo ambiri, wodzichepetsa. Polyethylene kawirikawiri amagwiritsidwa ntchito yomanga greenhouses ndi greenhouses kwa kutchinjiriza ndi konyowa-proofing wa zinthu zosiyanasiyana. Pa nthawi ntchito ya ambuye ambiri anakumana ndi kufunika kumata nkhaniyo. Apa ndi pamene mavuto ayamba. Mfundo yakuti polyethylene ndi kugwirizana bwino. Koma m'chitetezo adakali zotheka mothandizidwa ndi ulimbo. Ndi kupanga pansi zochita za kutentha. Kodi kusankha zomatira yoyenera polyethylene ndi kuti m'pofunika kulabadira kuntchito? Mafunso awa ndi zina mafunso angapezeke m'munsimu.

katundu wa polyethylene

zakuthupi ameneyu ali katundu zambiri zosangalatsa. Polyethylene ntchito kuchilango chinyezi ndi yabwino magetsi insulator ndipo amatha kungolandira imodzi mwa njira zoopsa kwambiri cheza. Ndi pafupifupi mwathunthu kugonjetsedwa ndi mankhwala. Ndi khalidwe lomaliza zina ulemu kwasanduka sangathe. Chisindikizo zinthu ndi mmene kusankha polyethylene zomatira?

N'zochititsa chidwi kulumikiza - si mankhwala, koma kumlingo ndondomeko magetsi. Mamolekyulu chikugwirizana zinthu amakopeka ndi mnzake chifukwa kusiyana milandu yawo. Choncho ndi kovuta kupeza chinthu chimene chimatsatira bwino kwa polyethylene anali, ndipo pambuyo atayanika wagwira molimba pamodzi ndalama angongole. Popeza mamolekyulu zakuthupi ndithu "moyenera", ndiye kumata zingakhale zovuta kwambiri ndi zinthu zina. Komabe, makampani mankhwala walenga ndi zomatira kwa kogwirizana polyethylene. Ndipo palibe mmodzi. zomatira bzin'funika adzatenga katundu wina. Tiyeni tiyang'ane pa izo ziri.

Zofunika zakuthupi zomatira

Ngati mwaganiza kumamatira polyethylene kapena penofenol (kuti mtundu wa thovu) ndi simenti kapena njerwa padziko, ndi yolusa zomatira wosanjikiza ayenera angapo katundu:

• Tikhale olimba ndi zotsatira za weathering.
• Musamuononge nkhani abraded.
• Digiri yapamwamba ya hygroscopicity ndi guluu wolimba kwambiri.
• Kukhala kugonjetsedwa ndi kutentha otsika.
• Ndi antiseptic ndi fungistatisticheskie khalidwe.
• Pitirizani katundu wawo kwa nthawi yaitali.

Ogula ndemanga kuti nawonso ndi ofunika powasamalira chitetezo chilengedwe zomatira ndi. Zimenezi n'zofunika kwambiri makamaka pamene ntchito zipangizo yokongola mkati. Ngati mukufuna kugwiritsa ntchito polyethylene (penofenol) mu saunas ndi kusinthika kapena osambira, tiyenera kulabadira zina kutentha zomatira kugonjetsedwa ndi kukana yake nthunzi ya madzi otentha.

Kodi kusankha guluu?

Ngati simukudziwa chimene mtundu wa zomatira polyethylene zabwino kwa inu, funsani wogulitsa kuyang'ana wina zomwe zikuphatikizapo methyl acrylate. Nkhanizi amapereka mofulumira olimbikitsa polyethylene ndi apamwamba kogwirizana. Komanso njira ingakhale monga chromic anhydride, zidulo zosiyanasiyana ndi xylene. Ubwino wosatsutsika wakuti zomatira izi kuti pamene inu ntchito simuyenera zina pamwamba chithandizo. Koma owerenga amanena kuti iye ali ndi chilema. Chotero polyethylene zomatira ndi poizoni kwambiri. Choncho, ntchito zonse bwino amaphikira panja. Chabwino, kapena kupereka khalidwe mpweya wabwino. Ndi bwino kumata "ntchito" pa kutentha +35 C. Sakuopa chinyezi, koma mosavuta akayaka.

Komanso masitolo angapezeke njira kulumikiza ma polima. Iwo amagulitsidwa mawonekedwe a phala wandiweyani. Amenewa anaphatikizapo zosungunulira zambiri amagwira. Pambuyo kugwirizana zigawo zikuluzikulu ziwiri, zomatira amapeza kapangidwe ankafuna. Monga zosungunulira ukuphwera mofulumira, ntchito osakaniza mwachangu. Kotero musati basi zimaswana kwambiri.

Koma neoprene zomatira kwa polyethylene ndi bwino ntchito. Chotero zikuchokera ndi yabwino kwambiri chifukwa olumikiza mphira kapena mbali rubberized neoprene nsalu, zikopa, anamva, ceramic, zitsulo, osakaniza iliyonse. Koma polystyrene, kukodzedwa polypropylene, polyethylene, ndi plasticized PVC ndi bwino ntchito. Palibe adzatero.

Akiliriki zomatira ndi filler ndi

Ngati simukudziwa chimene kumata polyethylene thovu, yesani kugwiritsa ntchito ziwiri zikuluzikulu pa maziko a methyl chomwecho. Kapenanso, mungathe kuyesa Easy-Mix Pe-PP Brand Weicon. Iwo ali katundu kwambiri guluu wolimba kwambiri. Izo ntchito kogwirizana polypropylene, polyvinylchloride ndi zipangizo zina polymeric. Pamene ntchito ndi zomatira ichi ndifulumire. Izo lofotokozabe ake katundu panja si kuposa mphindi zitatu.

Easy-Mix Pe-PP lili ndi zowonjezera ongokhala mikanda tosaoneka galasi. filler Izi sasiya zochitika za zomatira muzikondana. Choncho, msoko likukhalira silamphamvu. Chotero zomatira kwa thovu polyethylene ayenera okhawo ku ma CD choyambirira cha chosakanizira cha. Dito bwino pa kutentha +22 ° C. Full oipa anaonetsetsa osati kale kuposa maola 5-6.

epoxy zomatira

Ndithudi, izo si abwino kwambiri zomatira kwa kogwirizana polyethylene. Koma ngati simungathe kupeza kena kalikonse, mungayesere. Basi woyamba kukonza pamwamba:

1. M'mbali mwa magawo angongole "kuyeretsa" zabwino emery nsalu. Ndiye bwinobwino degrease iwo.
2. Onse mbali za ndondomeko ndi 20% njira ya anhydride chromic kapena yankho 25% dichromate potaziyamu. Ngati zinthu zimenezi sanapezeke, mungathe kugwiritsa ntchito njira amphamvu permanganate potaziyamu.
3. Pambuyo padziko kuchitira youma.
4. Kuchepetsa zomatira malinga ndi malangizo. Ikani wosanjikiza woonda wa pamalo kogwirizana. Pomwepo zimakocheza tsatanetsatane.
5. Tiyime kwa maola angapo, ndipo tsiku bwino - mpaka kumaliza solidification msoko.

ndemanga wosuta amasonyeza kuti utomoni phenol-formaldehyde ali guluu wolimba kwambiri kuti polyethylene. Kotero ngati inu kutsatira mosamala malangizo, mudzakhala bwino.

Kum'mamatira polyethylene: malangizo

Monga mukuonera, kumata polyethylene, ena amadziwa bwino simuyenera. Ndondomeko ntchito yomweyo bwino:

• kuyeretsa;
• degrease
• youma;
• kufalitsa zomatira zikuchokera;
• mbali chisindikizo;
• Makina;
• kusiya kuti ziume kwathunthu.

Pa nthawi yomweyo, mmene mungachitire ndi zinthu zina zilizonse poizoni, muyenera kuganizira za kukhalapo kwa magalasi oteteza, magolovesi ndi makina.
