yam ntxwv

Kev ua haujlwm tseem ceeb

a.Mechanical zog: siab zog, qaug zog tsis kam, seem stability, thiab me me creep (hloov tsawg heev nyob rau hauv kub kub);
b.Thaum tshav kub kub aging kuj: qhov txhim kho UL qhov ntsuas kub nce mus txog 120 ~ 140 ℃ (ntev kev laus sab nraum zoov kuj zoo heev);

c.Solvent resistance: tsis muaj kev ntxhov siab tawg;

d.Stability rau dej: yooj yim rau decompose nyob rau hauv kev sib cuag nrog dej (siv ceev faj nyob rau hauv high kub thiab high humidity ib puag ncig);

e.Kev ua haujlwm hluav taws xob:

1. Rwb thaiv tsev kev ua tau zoo: zoo heev (nws tuaj yeem tswj tau cov hluav taws xob ruaj khov txawm tias nyob hauv cov av noo thiab kub, nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim hluav taws xob thiab hluav taws xob qhov chaw);

2. Dielectric coefficient: 3.0-3.2;

3. Arc tsis kam: 120s

f.Moulding processability: txhaj tshuaj molding lossis extrusion molding los ntawm cov khoom siv zoo tib yam.Vim qhov ceev ceev crystallization ceev thiab zoo fluidity, pwm kub kuj tseem qis dua li ntawm lwm yam yas yas.Thaum ua cov txheej txheem nyias nyias, nws tsuas yog siv ob peb feeb xwb, thiab nws tsuas yog siv 40-60s rau qhov loj.

daim ntawv thov

a.Cov khoom siv hluav taws xob: cov khoom sib txuas, hloov qhov chaw, cov khoom siv hauv tsev, cov khoom siv, cov khoom siv hluav taws xob me me los yog (kub tsis kam, nplaim taws, hluav taws xob rwb thaiv tsev, molding processability);

b.Tsheb:

1. Sab nrauv: feem ntau suav nrog lub kaum sab xis, lub cav qhov cua npog, thiab lwm yam;

2. Sab hauv: feem ntau suav nrog endoscope nyob qis qis, wiper brackets thiab tswj qhov system li qub;

3. Automotive hluav taws xob qhov chaw: automotive ignition coil twisted hlab thiab ntau yam hluav taws xob connectors, thiab lwm yam.

c.Cov cuab yeej siv tshuab: siv lub tshuab tsav tsheb ntawm lub tshuab kaw lus video, lub tshuab hluav taws xob hauv lub computer, lub npog lub teeb mercury, lub npog hluav taws xob, lub tshuab ci ci thiab ntau lub zog, cams, khawm, hluav taws xob saib casings, lub koob yees duab qhov chaw ( nrog kub tsis kam, nplaim retardant yuav tsum)

Bonding

Raws li kev xav tau sib txawv, koj tuaj yeem xaiv cov nplaum hauv qab no:

1. G-955: Ib chav tsev kub curing soft elastic shockproof adhesive, resistant rau siab thiab tsis kub, tab sis lub sib txuas ceev ceev, cov kua nplaum feem ntau yuav siv sij hawm 1 hnub los yog ob peb hnub los kho.

2. KD-833 instant adhesive tuaj yeem ua sai sai rau PS yas hauv ob peb feeb lossis kaum vib nas this, tab sis cov nplaum txheej yog tawv thiab nkig, thiab nws tsis tiv taus cov dej kub immersion saum 60 degrees.

3. QN-505, ob-txhim kho cov kua nplaum, cov nplaum nplaum nplaum, tsim rau PS loj cheeb tsam kev sib txuas lossis kev sib txuas.Tab sis lub siab kub kuj tsis zoo.

4. QN-906: Ob-tivthaiv kua nplaum, kub tsis kam.

5. G-988: Ib qho khoom siv chav tsev kub vulcanizate.Tom qab kho, nws yog ib qho elastomer nrog zoo heev waterproof, shockproof nplaum, siab thiab kub tsis kam.Yog hais tias lub thickness yog 1-2 hli, nws yuav pib kho nyob rau hauv 5-6 teev thiab muaj ib tug tej lub zog.Nws yuav siv sij hawm tsawg kawg 24 teev kom kho tau tag nrho.Ib leeg-khoom, tsis tas yuav sib tov, tsuas yog siv tom qab extruding thiab cia nws sawv tsis muaj cua sov.

6. KD-5600: UV curing adhesive, bonding pob tshab PS nplooj ntawv thiab daim hlau, tuaj yeem ua tiav tsis muaj kab mob, yuav tsum tau kho los ntawm ultraviolet lub teeb.Cov nyhuv yog zoo nkauj tom qab lo.Tab sis qhov kub tsis kam yog qhov tsis zoo.

Khoom siv tau zoo

Cov rwb thaiv tsev hluav taws xob zoo heev (tshwj xeeb tshaj yog cov rwb thaiv tsev siab), tsis muaj xim thiab pob tshab, lub teeb xa tawm thib ob tsuas yog rau plexiglass, xim, dej tsis kam, tshuaj lom neeg ruaj khov, lub zog nruab nrab, tab sis nkig, yooj yim rau kev ntxhov siab brittleness, thiab intolerance Organic solvents xws li benzene. thiab roj av.Haum rau kev ua insulating pob tshab qhov chaw, cov khoom siv kho kom zoo nkauj, cov cuab yeej tshuaj, cov cuab yeej kho qhov muag thiab lwm yam.

Kev ua tau zoo

⒈Amorphous cov ntaub ntawv, tsis tshua muaj noo noo nqus, tsis tas yuav qhuav tag, thiab tsis yooj yim rau decompose, tab sis cov coefficient ntawm thermal expansion yog loj, thiab nws yog ib qho yooj yim los tsim kev nyuaj siab.Nws muaj qhov zoo fluidity thiab tuaj yeem ua los ntawm cov ntsia hlau lossis lub tshuab plunger txhaj tshuaj.

⒉ Nws raug nquahu kom siv cov khoom siv kub, pwm kub, thiab kev txhaj tshuaj tsawg.Kev ncua sij hawm txhaj tshuaj yog qhov zoo los txo cov kev ntxhov siab sab hauv thiab tiv thaiv shrinkage thiab deformation.

⒊ Ntau hom rooj vag tuaj yeem siv tau, thiab cov rooj vag txuas nrog cov khoom yas arc kom tsis txhob muaj kev puas tsuaj rau cov khoom yas thaum lub rooj vag raug tshem tawm.Lub demolding lub kaum sab xis yog loj thiab lub ejection yog uniform.Cov phab ntsa tuab ntawm cov yas yog qhov sib xws, nyiam dua yam tsis muaj qhov ntxig, xws li Qee qhov ntxig yuav tsum tau preheated.

siv

PS tau dav siv hauv kev lag luam kho qhov muag vim nws lub teeb xa hluav taws xob zoo.Nws tuaj yeem siv los tsim cov iav kho qhov muag thiab cov cuab yeej kho qhov muag, nrog rau cov xim pob tshab lossis cov xim ci, xws li cov teeb pom kev zoo, cov khoom siv teeb pom kev zoo, thiab lwm yam PS tuaj yeem tsim tau ntau yam khoom siv hluav taws xob thiab cov cuab yeej siv ua haujlwm nyob rau hauv ib puag ncig siab.Txij li thaum PS yas yog ib qho nyuaj-rau-inert nto khoom, nws yog ib qho tsim nyog yuav tsum siv cov kua nplaum PS los ua kev lag luam hauv kev lag luam.

Siv PS ib leeg ua ib yam khoom muaj siab brittleness.Ntxiv ib qho me me ntawm lwm yam tshuaj rau PS, xws li butadiene, tuaj yeem txo qhov brittleness thiab txhim kho qhov ua tau zoo.Cov yas no hu ua kev cuam tshuam-resistant PS, thiab nws cov khoom siv kho tshuab tau zoo heev.Ntau yam khoom siv thiab cov khoom siv nrog kev ua tau zoo yog tsim los ntawm cov yas.
