MQ Resin: Methyl / Phenyl & Mw Kgahlamelo ya PSA Kgomaretšo

Jiangsu Aokai New Materials , e etellang pele moetsi oa PTFE phahameng-mocheso theipi, u fa litsebi and analysis botekgeniki.

The polarity, steric tšitiso ea lihlopha manyolo le aggregation sebopeho sa liketane limolek'hule ka MQ silicone resin ke mabaka a motheo ho laola tshebetso teka-tekano ya silicone khatello-hlokolosi sekgomaretsi (PSA).Ka bokhutšoanyane: eketsa phenyl dikahare optimizes qalong tack, tšoara matla le peel matla ka nako e le nngwe; mola boima bja dimolekule le kabo ya boima bja dimolekule di latela molao wo o tlwaelegilego wa seesaw — boima bja dimolekule bjo bo phagamego bo kaonafatša maatla a go swara eupša bo dira sehlabelo ka tack ya mathomo; kabo ya boima bja dimolekule ka bophara ke tsela ye e šomago ya go lekalekanya dithoto tše tharo tša bohlokwa tša sekgomaretši.

1. Methyl / Phenyl Ratio: Peakanyo ya Tiragatšo ya ka gare ka Sebopego sa Dikhemikhale

Go tšeela karolo ya dihlopha tša methyl (-CH3) legato ka dihlopha tša phenyl (-C6H5) ke mokgwa wo o šomago wa phetošo ya maemo a dimolekule:

·  Enhanced intermolecular matla : The benzene lesale hlahisa matla π-π intermolecular sebelisana, haholo phahamisa matla cohesive ya sekgomaretsi, e leng motheo ntlafatsa tšoara matla le peel matla.

·  Eketsehile limolek'hule ketane rigidity : Phenyl dihlopha na le kgolo steric tšitiso, restricting potoloho ya silicone diketane ka sehloohong le ho fokotsa ketane tenyetseha. Se se hola go swara maatla eupša se na le tshekamelo ya go fokodiša tack ya mathomo.

·  Ntlafatswa wettability : Phenyl phetolo ntlafatsa kamano ya silicone PSA ho substrate bokagodimo, kgothaletsa segokanyimmediamentsi sa sebolokigolo tlamo, 'me ntlafatsa bobeli qalong tack le peel matla.

2. Boima bja Molekule & Kabo: Taolo ya Tiragatšo ka Mmele Entanglement & Aggregation State

Dihlopha tše di šomago di laola taolo ya dikhemikhale , mola boima bja dimolekule le kabo ya boima bja dimolekule (Polydispersity Index, PDI) di buša taolo ya mmele :

Boima ba Molekhule (Mw) .

Matla a kgokagano kudu a tšwa go go raragana ga mmele ga diketane tša polymer.

·  Mw e phagamego e bopa netweke ya go raragana ye e kitimago gomme e kaonafatša kudu maatla a go swara.

·  Mw ye e phagamego ka mo go feteletšego e dira gore diketane tša dimolekule di be thata le go se fetofetoge, go feletša ka go fokotšega ga maatla a tack le peel ya mathomo.

Kabo ya Boima bja Dimolekule (MWD) .

·  Mosesane kabo : Junifomo tshebetso, bonolo nepišitšwego optimization bakeng sa thepa e le 'ngoe tse kang phahameng qalong tack.

·  Kabo e nabilego : Go swana ga tshepedišo ya tlaleletšo. Dikarolwana tša boima bja dimolekule bjo bo phagamego di bopa marapo a netweke a thata go kgonthišetša matla a go kgokagana le matla a go swara; dikarolwana tša boima bja dimolekule bja fase di šoma bjalo ka ditlolo tša ka gare le diakgofi tša go kolobiša, di kaonafatša go sepela ga ketane le go kolobiša ka lebelo ga bokagodimo go netefatša tack ya mathomo ye botse, go fihlelela tshepedišo ye e lekalekanego ka kakaretšo.

3. Synergistic Optimization ya M / Q Ratio, Resin Tekanyetso le Silicone Rabara Viscosity

Karolelano ya methyl/phenyl le boima bja dimolekule di laola dithoto tša tlhago tša resin ya MQ; mola M / Q karolelano, resin ho silicone rabara karo-karolelano le silicone rabara viscosity ke ditekanyetos tobileng ho beakanya ka formula boenjiniere, e leng lokela ho matched synergistically.

Tekanyo ya M / Q

M / Q karo-karolelano ka ho toba laola boima ba limolek'hule, dikahare hydroxyl le lumellana le silicone rabara.The Optimum M / Q molar karo-karolelano bakeng sa silicone PSA ka kakaretso ke 0.6 ~ 1.2 .Ka mohlala, bongaka-mophato PSA adopts e Optimum M / Q boleng ba ka bang 0.78; resin le M / Q 0.6-0.9 kopantswe le silicone rabara (viscosity 100 × 10−4 m² / s) ka karo-karolelano boima ba 2: 3 fumana babatsehang akaretsang sekgomaretsi tshebetso.

Resin / Silicone Rabara Motswako Tekanyo

Karolelano ye ke lever ya senotlelo go lekalekanya dithoto tše tharo tša motheo (tack ya mathomo, maatla a go swara, maatla a go ebola).

·  Diteng tša resin tše di phagamego di kaonafatša kgokagano, maatla a go swara le maatla a go ebola eupša di fokotša tack ya mathomo.

·  Diteng tša rabara tše di phagamego di bontšha tshekamelo ye e fapanego.

Go fa mohlala, go godiša tekanyo ya boima bja resin ya MQ go raba ya silicone ya 107 go tšwa go 1.2 go ya go 2.5 go tla oketša maatla a go swara le maatla a go ebola a 180° mola go fokotša mathomo tack.In formulations sebetsang, karo-karolelano boima ba silicone resin ho silicone rabara hangata ke 45:55 ~ 75:25.

Silicone Rabara Viscosity

Boima bja dimolekule bjo bo bontšhitšwego ke viscosity bo laola dithoto tša motheo tša rheological tša tshepedišo ya sekgomaretši gomme bo hloka go sepelelana gabotse le MQ resin.Low-viscosity silicone rabber e na le go sepelelana gakaone le MQ resin, ye e loketšego go tack ya mathomo le maatla a go ebola, eupša e ka bea maatla a go swara kotsing.

4. Molaotheo wa Moralo wa Fomula bakeng sa Tekatekano ya Tiragatšo

Ka silicone PSA tlhamo moralo, tse tharo senotlolo indexes - qalong tack, tšoara matla, 180 ° ebola matla  - ka nepo laolwa ke tse peli konokono bolela:

·  Phenyl phetolo - multiplicative optimization : Proper phenyl doping ntlafatsa thepa tsohle tse tharo ka nako e le nngwe, roba setso seesaw thibelo.

·  Boima ba limolek'hule & kabo phetolo - additive kgwebo-off : Taolo e nepahetseng ya boima ba limolek'hule le kabo hlokomela customized teka-tekano pakeng tsa qalong tack le tšoara matla bakeng sa maemo a fapaneng kopo.

Ka tšweletšo ya intasteri, leano le le tlwaelegilego la formula ke kabo ya boima bja dimolekule ka bophara bja resin gotee le phetošo ya phenyl ye e lekanetšego  go lekalekanya processability le performance.For ya go kgomarela ye e feletšego.

Diteng tša botekgeniki tše di lego ka mo godimo di fiwa ke Jiangsu Aokai New Materials Technology Co., Ltd.

Haeba u batla ho tseba ditekanyetos qaqileng, maemo a kopo le ditharollo customized bakeng sa rona feletseng sehlahiswa mola: PTFE phahameng-mocheso lesela, PTFE phahameng-mocheso theipi, PTFE phahameng-mocheso letlooeng lebanta, seamless fusing mochine lebanta, lehlakoreng le le leng PTFE lesela, phahameng-mocheso manganga conveyor lebanta le phahameng-mocheso manganga fiberglass lesela, hle ikopanye le rena:
