Glue for polypropylene and polyethylene

Polypropylene uye polyethylene zvinhu zvakakosha kusungira. Kana iwe usingashandisi kutengesa, ipapo nzira yekubatanidza zvinhu zviviri ichave yakaoma. Pakati pezvimwe zvinhu, nzvimbo yacho inoda kutanga kutanga kudzidzira. Zvimwewo, anotsigira inogona kushandiswa kwe polypropylene.

Mhando mikuru yematevedzo

Kana uchida glue yepurasitiki, unofanira kuziva kuti ine zvinhu zviviri: thermosetting uye thermoplastic yakagadzirwa. Epoxy, thermosetting uye polyester resin inoshanda sechikonzero chekutanga. Chikamu chechipiri cheglues chinogona kugoverwa kuita maviri, iyo yekutanga inogadzirwa pamusana pehupfumi, asi yechipiri inobva pane zvinyorwa.

Inormoplastic compositions inoderedza zvinhu uye inopera pasi pesimba rekushisa. Kana tikazvienzanisa ne thermoset, hazvisi kuchinja maitiro emakemikari kana akabatanidzwa, izvo zvinokosha pamwe chete. Nhengo ye polypropylene inogonawo kugoverwa maererano nehuwandu hwezvikamu, iyo mizinga inogona kuva imwe-kana maviri-chikamu. Yokutanga inowanikwa muzvigadziro zvakagadzirwa mune imwe puragi. Izvi zvinosanganisira glue "Nguva" ye polypropylene. Uye yechipiri yakatunganidzwa mumapathoroji maviri, rimwe nerimwe rine zvigadzirwa zvekusanganiswa. Semuenzaniso wehumwechete-hutachiona, Cosmoplast 500 inogona kufungwa, iyo inoshandiswa kujoina mapurogiramu mukugadzira hwindo. Kana uchida kuumbwa kwemaviri, iwe unogona kushandisa epoxy adhesive yepurasitiki, iyo inogadzirwa pamusana pekuoma uye epoxy resin. Zvinyorwa zviviri-chikamu chinobatsira, izvo zvinoratidzwa muhupenyu hurefu refu. Chikonzero chacho ndechokuti musati mutevedzo zvishandiso hazvitauri uye zvakasimba hazviitike.

Idzi hukuru hunhu hweCosmoplast 500 glue

Mushonga wepamusoro unonzi polypropylene unoshanda sechikamu chimwe chezvikamu, izvo zvinogona kushandiswa mumashini uye muupenyu hwezuva nezuva. Inogona kushandiswa kusungira majoini paakona ye 45 °. Iko kusanganiswa kwakakwirira kune yakafanana nayo yenguva shoma yekuoma. Izvo zvakagadzirwa zvinopesana nemvura, kutonhora nekupisa. Nguva yekuoma ndeyemashure matatu, uye nguva yekupedzisira yakaoma pa20 ° C maawa gumi nemaviri.

Kushandisa mirayiridzo Cosmoplast 500

Kana ukasarudza kushandisa zvakasungirwa pamusoro pe polypropylene, unofanira kutanga uzviziva nemhando dzekushandisa kwayo. Shandisa musanganiswa kubva pane chiyero chekuyera kana pamwe chete neCosmoplast CA, iyo iri chiyero chekuyera. Chirongwa chacho chinofanira kuitwa kune rumwe rutivi rwepamusoro, iyo inofanira kutanga yakanatswa tsvina uye guruva, uye yakaoma. Kuchenesa kunogona kuitwa nekubatsirwa kwemashoko anokosha akadai "Kosmofen 60". Kupera kunofanira kushamwaridzana uye kunomanikidzirwa kune imwe nguva isati yaoma mumhepo. Pamusana pepasi reascotosity, zvakasanangurwa zvinorondedzerwa hazvikwanise kumira kukanganiswa kweganda rekunamatira. Kana pane chido chekubatanidza zvikwereti zvakakura, ipapo pakunoda, Cosmoplast 564 inogona kushandiswa.

Kuchenesa glue

Iyo glue yekubatanidza polypropylene inogona kucheneswa mune imwe nguva isati yakasungwa pamwe nekubatsirwa kwegadziriro "Kosmoplast 597". Kushambidza kwekugadzira chigadziko kubva glue isina kuswa inoitwa pamwe nekubatsirwa nenzira imwe chete. Kana glue rave raoma, zvino rinogona kucheneswa pamunhu. Apo zvisikwa zvine chando, iyo yakatomwa yakaomarara inogona kubviswa zvachose.

Zvichemo zvekushandiswa

Kuisa chisimbiso kunzvimbo kunofanira kunge kunopera, kunatswa uye kuomeswa. Degreasing inokwanisika nemasvokita akaita seaketone kana isopropyl alcohol. Nhamba yakakwana ye sealant inofanira kushandiswa kune imwe yezvisikwa, uye zvino shandisa mabhesi maviri. Kururamisa nzvimbo yezvikamu kunogona kuitwa mukati maminitsi gumi nemashanu mushure mokushandisa, kusvikira firimu yakaumbwa pamusoro pekunamatira. Kana mamiriro ekushisa kwemukati uye hunyoro hwechikamu hwe50% huri kugutsikana, ipapo huwandu hwekudya hunenge huri mamiriyoni pazuva. Kana hunyoro hukaderedzwa, nguva yekudira ichawedzera.

Zviratidzo zvekubatanidza zvikamu zviviri WEICON Easy-Mix PE-PP

Izvo zvakakanganwa ishamwari mbiri-inhengo ye gluing polypropylene uye polyethylene. Inogadzirwa pamusana peacrylate uye ine yakasimba yokunamatira simba yepasi-plastiki uye plastiki. Zvakakosha kuti kutanga kushandiswa kwebasa hakudi. Izvi zvakasikwa zvachose, saka zvinogona kushandiswa kwegluing polyamide, polyvinyl chloride, polycarbonate, polymethyl methacrylate, pamwe nemagetsi egirazi nezvimwe zvinhu.

Mhedziso

Kana ukashandisa imwe yezvinyorwa zvinorondedzerwa pamusoro apa, unoronga kusungira polypropylene mapaipi, saka kutonhorera muimba yacho kunofanira kuva mumakiromita kubva pa55 kusvika ku35 ° C. Zvakakosha kuva nepfuti yeglue, brashe yakagadzirwa nemasikirwo emasikirwo, uye pipe cutter. Usati washandisa kuumbwa kwekubatanidza, mitsara yezvikamu inofanira kubviswa, nenzira iyi chete ichave yakakwanisa kuwana kuvimbika kwakasimba kwekubatana.
