Ezinepolypropylene enamathelayo kunye polyethylene

Polypropylene kunye polyethylene yinto, ezo kakhulu nzima ukuze libanike ubuhlobo. Ukuba awufuni ukusebenzisa welding, inkqubo odibanisa izinto ezimbini iza kuba yingxaki. Phakathi kwezinye izinto, imiphezulu kufuneka ukulungiselela yethutyana ekuqaleni. Le ngcina ingasetyenziselwa ezinepolypropylene kungenjalo.

Eyona engundoqo iintlobo ze yokuncamathelisa

Ukuba ufuna i iglu ngenxa zeplastiki, ufanele wazi ukuba ifike ntlobo ezimbini: thermoset kunye nokwakheka thermoplastic. Njengesiseko le epoxy isenzo sokuqala, yaye ipholiyesta thermoset nentlaka. Udidi lwesibini yokuncamathelisa lungohlulwa lube kwiindawo ezimbini, owokuqala wenziwa ngenxa iirubber, ngoxa yesibini - ngokusekelwe nentlaka.

Ukuqamba Thermoplastic igwebu ucombulule izinto phantsi kwempembelelo lobushushu. Ukuba ezifanisa kunye thermosetting, bona musa ukutshintsha isakhiwo yemichiza lwabo ngethuba ubuhlobo, nto leyo a inzuzo enkulu. ezinepolypropylene enamathelayo zingahlukaniswa nokuba kwaye inani yeekhomponenti kwimixube ezinjalo inokuba mono- okanye bicomponent. Okokuqala kuboniswa imveliso ogqityiweyo kwi package mnye. Ezi ziquka glue "Moment" ukuze ezinepolypropylene. A yesibini zahlanganiswa iipakethe ezimbini, nganye kuzo eziqulathwe izithako ukuba mix. Ngokomzekelo, cinga indlela-icandelo elinye ukwakheka angakwazi Cosmoplast 500 esetyenziselwa ukudibanisa iiprofayili kwi window ukwenziwa. Ukuba ufuna candelo-mbini, kunokwenzeka ukuba usebenzise iglu epoxy ngenxa iplastiki, nto leyo senziwa ngokususela arhente ayengawokuphilisa kunye epoxy nentlaka. -Component ezimbini kwakuse esinokusibambisa, nto ichazwa ngendlela yokugcina ixesha elide. Isizathu kukuba izithako ningangeni qha eselapha awufumaneki phambi kokuxhuma.

iimpawu eziphambili Cosmoplast ngcina 500

Le ezinepolypropylene enamathelayo ekhankanywe ngasentla isebenza sisincoko olunye-component ezinokusetyenziswa kushishino kunye nobomi bemihla ngemihla. Kokuba isicelo unxibelelwano lib kwi-engile 45 °. Lo mxube bongamile kunoogxa babo ixesha elifutshane yokomisa. Ukubunjwa iyamelana namanzi, ubushushu nengqele. Esondele ixesha layo yokomisa eyi-3, kwaye ngexesha ayengawokuphilisa yokugqibela-20 ° C ziiyure-16.

Operating Imiyalelo 500 Cosmoplast

Ukuba ugqiba ekubeni usebenzise iglu echazwe ngentla-kuba ezinepolypropylene, kufuneka kuqala ungaqhelani ukusetyenziswa kwayo. Yenza umxube kufuneka ukuba umlinganiselo isikhongozeli okanye kunye Cosmoplast kohlobo kuthetha leyo sisixhobo wekhadi. Esi sicelo kufuneka senziwe kwelinye umphezulu nangapha, nto leyo kuyimfuneko ngaphambili ukucoca ukusuka ukungcola nothuli, kwaye zonekwe. Ukucoca kungenziwa ngoncedo izixhobo ezizodwa uhlobo "Kosmofen 60". Imiphezulu ukuba wazihlanganisa phantsi uxinzelelo ixesha elithile phambi kokuba yaphuse ngaphandle. Ngenxa viscosity eliphantsi ubume echazwe abakwazi ukumelana uxinzelelo isikhewu yesondo. Ukuba ufuna ukudibanisa emathutyeni enkulu, ukuba ingasetyenziswa ngokokubona Cosmoplast 564.

Ukucoca le ngcina

Le ngcina for ekwakheni le ezinepolypropylene inokuba nyulu ngakumbi usebenzisa ukulungiselela nezasohshem "Kosmoplast 597". Ukuhlamba umthamo ngokomthamo of ngcina nezasohshego kuthwalwa ngendlela efanayo. Ukuba le ngcina sele ikwazile ukuba yome, ngoko unga ce ngesandla. Xa imiphezulu eziquka inyityilikiswayo, le ngcina kube sele esomileyo zisuswe ngokupheleleyo.

Iimpawu izitampu sealant-enamathelayo Dow Corning 7091

Oku kwakuse-sealant ukuba ezinepolypropylene yi ubunzima fluid viscous esetyenziselwa uphawu amalungu kunye nokhuselo kwiindawo ezahlukeneyo. Indlela ezakhiwe ngayo kusetyenziswa izinto nisondelelane yohlobo olunye kunye nezinye. Phakathi iimpawu eziphambili iglu zingahlukaniswa, ngolu hlobo lulandelayo:

• ukukwazi uphawu kwaye odibanisa izinto ezahlukeneyo;
• ukufudumeza ukumelana;
• ukumelana yelanga eyingozi;
• kwalo;
• adhesion High kwimathiriyeli ezahlukeneyo;
• okubuyela kwimo ephezulu omhlophe.

Kufuneka kukhunjulwe ukuba sealant ukuze ebalasele uhlobo enganyangekiyo acid, oku kubonisa ukuba ubume uyakwazi isixa esithile acetic acid ngexesha Ukuqinisa. Oku kunokubangela ukutshatyalaliswa zesinyithi non-ayoni umhlwa wazo. Oku kufuneka kubandakanye marble kunye nezinye izinto. Oku kwakuse sikhona yonke, kuya kuba lula yaye kulula ukuyisebenzisa, na iimpawu yokuxhathisa amanzi kunye ukuxhathisa iikhemikhali ukungcangcazela. Oku kungenziwa eziqhutshwa kwiqondo lobushushu lwe ukususela -55 ukuya +180 ° C. Le iglu iimpiliso a ezinepolypropylene transparent bushushu, iye adhesion elungileyo ngaphandle priming ezongezelelweyo izinto eziqhelekileyo. Ukubunjwa uyakwazi ukwenza indima iglu maleko ububanzi 5 mm, oko zingasetyenziswa njenge sealant, ukuba umaleko ukuze zenze ukuya kwi-25 mm. Xa isicelo limele inductile pasty guquki. Emva kokugqitywa inyathelo lukhuni ukuyondelelana ifana irabha elastic. Phakathi iimpawu ezifunekayo ukuze kubabela elo sealability izinto yohlobo olunye kunye nabo thermal ukwanda ingumlingani ezahlukeneyo.

Kutheni ukukhetha uhlobo sealant Dow Corning 7091

Le ngcina echazwe-ngasentla ezinepolypropylene kunye polyethylene ayiphetheyo ukunganyangeki oyile iimpawu, ukumelana ukufuma, okubuyela kwimo ephezulu kunye namandla. Kulula ukuba isicelo, phakathi kwezinye izinto, ikwazi ukwenziswa into lobushushu ukususela -55 ukuya +180 ° C.

Iimpawu ze isicelo

Imiphezulu uphawu kufuneka degreased, ucocwe kwaye zonekwe. Bamafutha kunye pende mhlawumbi yi uhlobo acetone okanye utywala isopropyl. Imali efunekayo sealant kufuneka isetyenziswe komhlaba mnye, uze uqhagamshele neenqwelwana ezimbini. Lungisa ilungiselelo efanayo yeekhomponenti kuba phakathi kwemizuzu eli-15 emva kokuba isicelo de ifilim kwakheka kwi kumphezulu ngcina. Ukuba imiqathango ithotyelwe ukuba lobushushu igumbi kunye nokufuma isalamane-50%, isantya ayengawokuphilisa iya kulingana kangangeemitha ezi-2 ngosuku. Ukuba isiqulatho ukunyakama lifinyele, ixesha Ukuqinisa uza kunyuka.

Iimpawu WEICON Easy-Mix PE-PP bicomponent glue

Le ukwakheka ngumxube licandelo-ezimbini lib polyethylene kunye ezinepolypropylene. It senziwa kwisiseko acrylate, kwaye amandla aphezulu enamathelayo zeplastiki ezisezantsi-amandla iiplastiki. Kuyaphawuleka ukuba umphezulu pretreated ayikho imfuneko. Le yokuqamba enemisebenzi, ngoko inokusetyenziswa ukuba lib le polyamide, Polyvinyl chloride, polycarbonate, eqobekayo बिट्स, kwakunye fiberglass kunye nezinye izinto.

isiphelo

Xa usebenzisa omnye ezaqanjwa ngasentla ufuna uncamathelise kwimibhobho ezinepolypropylene, iqondo lobushushu igumbi kufuneka ibe iindidi ukususela +5 ukuya +35 ° C. Kubalulekile ukuba umpu iglu, ibhrashi kunye ezifumaneka zendalo, ngokunjalo mgawuli umbhobho. Ngaphambi kokuba nokusebenzisa i amacandelo edge enamathelayo kufuneka enziwe mpuluswa phandle, ekuphela kwendlela uya kukwazi ukufumana ukuthembeka komphetho eliphezulu.
