MQ Resin: Methyl / Phenyl & Mw Ingaruka ya PSA

Jiangsu Aokai Ibikoresho bishya , biyoboye uruganda rukora kaseti ya PTFE yubushyuhe bwo hejuru, biguha isesengura ryubuhanga.

Ubuharike, inzitizi zikomeye zamatsinda kama hamwe nuburyo bwo kwegeranya iminyururu ya molekile muri resin ya MQ silicone nimpamvu zingenzi zoguhuza imikorere yimikorere ya silicone yumuvuduko ukabije wamavuta (PSA) .Muri make: kongera fenili yibintu byoroha gukemura, gufata imbaraga hamwe nigishishwa icyarimwe; mugihe uburemere bwa molekuline hamwe no gukwirakwiza uburemere bwa molekuline bikurikiza amategeko asanzwe - uburemere buke bwa molekile butezimbere gufata imbaraga ariko bigatanga igitambo cyambere; gukwirakwiza uburemere bwa molekuline nuburyo bwiza bwo kuringaniza ibintu bitatu byingenzi bifata.

1. Igipimo cya Methyl / Phenyl: Guhindura imikorere yimbere binyuze mumiterere yimiti

Gusimbuza igice cyamatsinda ya methyl (-CH3) hamwe nitsinda rya fenyl (-C6H5) nuburyo bwiza bwo guhindura urwego rwa molekile:

·  Kongera imbaraga za intermolecular : Impeta ya benzene itanga imikoranire ikomeye π-π intermolecular, ikazamura cyane imbaraga zifatika zifatika, zitezimbere muburyo bwo gufata imbaraga nimbaraga zishishwa.

·  Kongera urunigi rukomeye : Amatsinda ya fenyl afite imbogamizi nini ya steric, igabanya kuzenguruka iminyururu nyamukuru ya silicone no kugabanya urunigi. Ibi bifata gufata imbaraga ariko bikunda kugabanya intege zambere.

·  Kunonosora neza : Guhindura fenyl byongera umubano wa silicone PSA kugirango uhindure ubuso, utezimbere guhuza imiyoboro, kandi utezimbere imbaraga zambere hamwe nigishishwa.

Amatsinda akora yiganjemo kugenzura imiti , mugihe uburemere bwa molekile no gukwirakwiza uburemere bwa molekile (Polydispersity Index, PDI) byiganje kumubiri :

Uburemere bwa molekile (Mw)

Imbaraga zifatika ahanini zituruka kumubiri wumurongo wa polymer.

·  Mw Yisumbuye ikora umuyoboro wuzuye kandi utezimbere cyane gufata imbaraga.

·  Mw birenze urugero Mw ituma iminyururu ya molekile ikomera kandi idahinduka, bigatuma kugabanuka kwambere hamwe nimbaraga zishishwa.

Ikwirakwizwa ryibiro bya molekulari (MWD)

·  Gukwirakwiza muri make : Imikorere imwe, byoroshye intego yo gutezimbere kumitungo imwe nkibisubizo byambere.

·  Gukwirakwiza kwagutse : Guhuza imikorere yuzuye. Ibice byinshi-bifite uburemere buke bigize urusaku rukomeye rwa skeleton kugirango yizere imbaraga zifatika no gufata imbaraga; Ibice bito-bifite uburemere buke bikora nk'amavuta yo kwisiga imbere hamwe no kwihuta kwihuta, kunoza urujya n'uruza rwihuta kugirango habeho gukemura neza, kugera kubikorwa byuzuye.

Ikigereranyo cya Methyl / fenyl hamwe nuburemere bwa molekuline bigena imiterere yihariye ya MQ resin; mugihe M / Q igereranyo, resin kuri silicone reberi na silicone rubber viscosity ni uguhindura ibipimo muburyo bwa tekinoroji, bigomba guhuzwa hamwe.

Ikigereranyo cya M / Q.

Ikigereranyo cya M / Q kigena mu buryo butaziguye uburemere bwa molekile, ibirimo hydroxyl no guhuza na reberi ya silicone. Ikigereranyo cyiza cya M / Q molarike ya silicone PSA muri rusange ni 0,6 ~ 1.2 .Urugero, PSA yo mu rwego rw’ubuvuzi ifata agaciro ka M / Q kangana na 0,78; resin hamwe na M / Q 0.6–0.9 yongewemo na reberi ya silicone (viscosity 100 × 10⁻⁴ m² / s) ku kigereranyo cya 2: 3 ibona imikorere myiza yo gufatira hamwe.

Ikigereranyo / Silicone Rubber Ikigereranyo

Iri gereranya nurufunguzo rwo kuringaniza ibintu bitatu byingenzi (tack yambere, gufata imbaraga, imbaraga zishishwa).

·  Ibirimo byinshi bya resin bitezimbere ubumwe, bifata imbaraga nigishishwa ariko bigabanya gutangira.

·  Ibikoresho byo hejuru bya reberi byerekana inzira zinyuranye.

Kurugero, kuzamura igipimo kinini cya resin ya MQ kuri rebero ya silicone 107 kuva kuri 1.2 ikagera kuri 2.5 bizongera imbaraga zo gufata hamwe nimbaraga za 180 ° mugihe bigabanutse kubanza tack.Mu buryo bufatika, igipimo rusange cya silicone resin na silicone reberi ni 45:55 ~ 75:25.

Silicone Rubber Viscosity

Uburemere bwa molekuline bugaragazwa nubwiza bugena imiterere yibanze ya rheologiya ya sisitemu ifata kandi ikenera guhuza neza na resin ya MQ.Icyuma cya silicone ya silicone ntoya ihuza neza na resin ya MQ, ikagira imbaraga zo gutangira imbaraga hamwe nigishishwa, ariko irashobora kubangamira gufata imbaraga.

4. Ihame rya Igishushanyo mbonera cyo Kuringaniza Imikorere

Mu gishushanyo mbonera cya silicone PSA, ibipimo bitatu byingenzi - icyerekezo cyambere, gufata imbaraga, 180 ° imbaraga zishishwa  - birashobora kugengwa neza nuburyo bubiri bwibanze:

·  Guhindura fenyl - kugwiza ibintu byinshi : Doping ikwiye ya fenil itezimbere imitungo uko ari itatu icyarimwe, ikuraho imipaka gakondo.

·  Uburemere bwa molekulari & gukwirakwiza - kongera ibicuruzwa byongeweho : Kugenzura neza uburemere bwa molekile no kugabura byerekana uburinganire bwihariye hagati yuburyo bwambere hamwe no gufata imbaraga kubintu bitandukanye.

Mu musaruro w’inganda, ingamba zihuriweho ni uburyo bwagutse bwo gukwirakwiza ibiro bya resin hiyongereyeho fenyl igereranije  kugirango ihindurwe neza kandi ikore neza. Kubireba ubushyuhe bukabije bw’ubushyuhe bukabije hamwe n’ibidukikije bikomoka ku miti, ibinyabuzima byinshi bya fenilike birimo MQ resin niwo muti watoranijwe.

Ibikoresho bya tekinike byavuzwe haruguru bitangwa na Jiangsu Aokai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Niba ushaka kumenya ibipimo birambuye, ibyasabwe hamwe nibisubizo byabigenewe kumurongo wuzuye wibicuruzwa: PTFE imyenda yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE wubushyuhe bwo hejuru, umukandara wimashini udahuza, umwenda wa PTFE uruhande rumwe, umukandara wa convoyeur wihanganira ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, nyamuneka twandikire:
