Adhesive polypropylene thiab polyethylene

Polypropylene thiab polyethylene yog cov ntaub ntawv, uas yog heev yooj yim mus muab nyob rau hauv tsevneeg. Yog hais tias koj tsis txhob siv welding, tus txheej txheem ntawm txuas rau ob tug hais yuav tsum problematic. Ntawm lwm yam, qhov chaw xav tau kev provisional pib npaj. Cov nplaum tej zaum yuav siv tau rau polypropylene xwb.

Lub ntsiab ntawm ntau yam adhesives

Yog hais tias koj xav tau ib tug nplaum rau yas, koj yuav tsum paub hais tias nws los nyob rau hauv ob flavors: thermoset thiab thermoplastic muaj pes tsawg leeg. Raws li ib lub hauv paus ntawm cov thawj ua epoxy, thiab polyester thermoset cob. Qhov thib ob qeb ntawm adhesives yuav tau muab faib mus rau hauv ob qhov chaw, tus thawj yog ua lub hauv paus ntawm roj hmab, thaum lub sij hawm thib ob - nyob rau hauv lub hauv paus ntawm resins.

Thermoplastic compositions muag thiab yaj ntaub ntawv nyob rau hauv tus ntawm kub. Yog hais tias los sib piv nrog thermosetting, lawv tsis hloov lawv cov tshuaj qauv thaum lub sij hawm ua ke, uas yog ib tug tseem ceeb kom zoo dua. Adhesive polypropylene yuav tau muab faib txawm thiab tus naj npawb ntawm Cheebtsam ntawm xws mixtures tej zaum yuav mono- los yog bicomponent. Thawj hais raws li ib tug tiav lawm khoom nyob rau hauv ib tug pob. Cov no muaj xws cov kua nplaum "Caij" rau polypropylene. Ib tug thib ob fej nyob rau hauv ob pob khoom, txhua tus uas muaj cov khoom xyaw kom sib tov. Raws li ib qho piv txwv, xav txog ib tug ib-feem muaj pes tsawg leeg tau Cosmoplast 500 uas yog siv los txuas rau lub profiles nyob rau hauv lub qhov rais siv thiab ua. Yog hais tias koj xav tau ib tug ob-tivthaiv, nws yog tej zaum yuav siv ib tug epoxy nplaum rau yas, uas yog ua rau lub hauv paus ntawm lub curing neeg saib xyuas thiab epoxy cob. Ob-tivthaiv nplaum muaj lub zoo dua, uas yog qhia nyob rau hauv ib tug ntev lub sij hawm cia. Yog vim li cas yog hais tias cov khoom xyaw tsis tuaj mus rau hauv kev sib cuag thiab ruaj khov tsis tshwm sim ua ntej txuas.

Main yam ntxwv Cosmoplast nplaum 500

Qhov saum toj no-hais nplaum polypropylene ua raws li ib tug ib-feem muaj pes tsawg leeg uas yuav siv tau nyob rau hauv kev lag luam thiab lub neej txhua hnub. Nws yuav tsum muaj ntaub ntawv rau tsevneeg sib txuas ntawm lub kaum sab xis ntawm 45 °. Qhov no sib tov yog superior rau lawv cov counterparts nyob rau hauv ib tug luv luv kom qhuav lub sij hawm. Cov nyob tus yeees yog resistant rau cov dej, Thaum tshav kub kub thiab txias. Kwv nws kom qhuav lub sij hawm yog 3 vib nas this, thiab thaum lub sij hawm kawg curing nyob rau hauv 20 ° C yog 16 teev.

Kev khiav hauj lwm Cov lus qhia 500 Cosmoplast

Yog hais tias koj txiav txim siab siv cov saum toj no-piav cov nplaum rau cov polypropylene, nws yuav tsum xub tau paub nrog nws siv. Thov lub sib tov yuav tsum yog los ntawm ntsuas lub ntim los yog ua ke nrog Cosmoplast parser txhais tau tias uas yog ib tug metering ntaus ntawv. Daim ntawv thov yuav tsum tau ua nyob rau ib sab nto, uas yog yav tas los tsim nyog los ntxuav los ntawm cov av thiab plua tshauv, thiab qhuav. Ntxuav yuav ua tau nrog kev pab los ntawm tshwj xeeb cov cuab yeej rau hom "Kosmofen 60". Lub chaw yuav tsum tau tuaj koom thiab raug siab rau ib lub sij hawm ua ntej kom qhuav nraum zoov. Vim cov uas tsis muaj viscosity ntawm muaj pes tsawg leeg piav tsis tau mas nro Bonded kis. Yog hais tias koj yuav tsum tau txuas rau tus loj khoob, nws yuav siv tau nyob rau kev txiav txim ntawm Cosmoplast 564.

Ntxuav tau cov kua nplaum

Cov nplaum rau tsevneeg lub polypropylene yuav muaj kev dawb huv ntxiv siv ib tug nezasohshem npaj "Kosmoplast 597". Ntxuav volumetric peev xwm ntawm nezasohshego nplaum nqa los ntawm tib lub txhais tau tias. Yog hais tias lub nplaum twb muaj kev tswj kom qhuav tawm, ces koj yuav ntxuav nws los ntawm txhais tes. Thaum qhov chaw comprise hnyav, lub nplaum yuav twb qhuav kiag li tshem tawm.

Cov yam ntxwv ntawm cov sealant-nplaum nyiaj muas Dow Corning 7091

Qhov no nplaum-sealant rau polypropylene yog ib tug khov dej loj uas yog siv los muab cov pob qij txha thiab kev tiv thaiv los ntawm ntau yam chaw. Muaj pes tsawg leeg yuav siv tau rau tsevneeg ntaub ntawv homogeneous nrog txhua lwm yam. Ntawm cov ntsiab yam ntxwv ntawm lub nplaum peev xwm yuav txawv, raws li nram no:

• muaj peev xwm mus muab thiab muab ntaub ntawv sib txawv;
• thaum tshav kub kub kuj;
• kuj mus ultraviolet rays;
• durability;
• High adhesion rau ntaub ntawv sib txawv;
• siab elasticity ntawm lub leeg.

Nws yuav tsum tau nco ntsoov tias sealant yuav tsiag ntawv los ntawm ib tug acid curing hom, qhov no qhia tau hais tias muaj pes tsawg leeg muaj lub peev xwm los faib ib qhov nqi ntawm cov acetic acid thaum lub sij hawm solidification. Qhov no yuav ua rau cov kev puas tsuaj uas tsis yog-ferrous co thiab lawv corrosion. Qhov no yuav tsum tau muaj xws li marble thiab ib co lwm yam ntaub ntawv. Qhov no nplaum yog universal, nws yog yooj yim thiab yooj yim rau siv, muaj cov qualities ntawm dej kuj thiab kuj mus tshuaj thiab kev co. Nws yuav ua rau ntawm ib tug kub ntawm los ntawm -55 mus +180 ° C. Qhov no lo cures mus rau ib tug pob tshab polypropylene ntawm chav tsev kub, nws muaj zoo adhesion tsis muaj ntxiv priming nrog pa ntaub ntawv. Cov nyob tus yeees yog tau ua lub luag hauj lwm ntawm ib tug nplaum txheej thickness ntawm 5 hli, nws yuav siv tau raws li ib tug sealant, yog hais tias tus txheej tsim txog li 25 hli. Thaum ua ntawv thov nws nruab nrab yog inductile pasty taub hau. Tom qab kawm tiav ntawm lub hardening kauj ruam lub taub hau tsa ib tug elastic roj hmab. Ntawm cov qualities tsim nyog los faib lub sealability ntawm homogeneous cov ntaub ntawv thiab cov neeg uas muaj ntau thermal expansion coefficient.

Yog vim li cas xaiv ib tug sealant hom Dow Corning 7091

Qhov saum toj no-piav cov nplaum rau cov polypropylene thiab polyethylene muaj qualities roj kuj, ua hauj dej, siab elasticity thiab lub dag lub zog. Nws yog ib qho yooj yim mus ua ntawv thov, inter alia, nws muaj peev xwm sawv ntawm niaj ib tug kub ntawm los ntawm -55 mus +180 ° C.

Nta ntawm daim ntawv thov

Cov kev sib khi chaw yuav tsum tau degreased, ntxuav thiab qhuav. Degreasing nrog cov kuab tshuaj tejzaum los ntawm hom acetone los yog isopropyl haus dej cawv. Qhov yuav tsum tau npaum li cas sealant yuav tsum tau ua ntawv thov mus rau ib nto, thiab ces txuas lub ob bases. Kho lub kev sib nrig sib kho ntawm lub Cheebtsam yuav ua tau tsis pub dhau 15 feeb tom qab daim ntawv thov kom txog rau thaum ib tug zaj duab xis yog tsim nyob rau hauv lub nplaum nto. Yog hais tias tus mob uas tau ntsib rau chav tsev kub thiab ib tug txheeb ze humidity ntawm 50%, cov curing ceev yuav ua ncaj rau 2 meters ib hnub twg. Yog hais tias noo cov ntsiab lus yog txo, lub solidification lub sij hawm yuav ua rau kom.

Cov yam ntxwv WEICON qho yooj yim-Mix PE-PP bicomponent lo

Qhov no muaj pes tsawg leeg yog ib tug ob-feem sib tov rau tsevneeg polyethylene thiab polypropylene. Nws yog tsim nyob rau hauv lub hauv paus ntawm acrylate, thiab muaj ib tug high nplaum quab yuam ntawm tsawg-zog yas thiab yas. Nws yog noteworthy tias cov pretreated nto yog tsis tsim nyog. Qhov no muaj pes tsawg leeg yog ib tug ntau yam, li ntawd nws yuav siv tau rau cov tsevneeg ntawm cov Polyamide, polyvinyl tshuaj dawb, polycarbonate, polymethyl methacrylate, raws li zoo raws li fiberglass thiab lwm yam ntaub ntawv.

xaus

Thaum siv ib tug ntawm cov saum toj no compositions koj xav muab tus polypropylene hlab, qhov kub ntawm lub chav tsev yuav tsum nyob rau hauv lub chav los ntawm +5 rau +35 ° C. Tseem ceeb kom muaj ib tug kua nplaum phom, ib tug txhuam nrog tej yam ntuj tso twg, raws li zoo raws li ib tug yeeb nkab cutter. Ua ntej thov kev lub nplaum ntug seem yuav tsum tau smoothed tawm, tsuas yog txoj kev yuav tsum tau mus nrhiav tau siab ntseeg leeg.
