Ni ubuhe butumwa bwandikirwa hagati ya gel agace kerekana ibice bya silicone yumuvuduko ukabije wimbaraga hamwe nimbaraga zifatika zurwego rufatika?

I. Ibisobanuro nuburyo bwo gupima Ibipimo

1. Igice cya Gel:

   Igice cya jel bivuga ijanisha ryinshi ryurusobe rwuzuzanya muri silicone yumuvuduko ukabije wometse kuri Teflon yubushyuhe bwo hejuru budashobora gukemuka mumashanyarazi meza (nka toluene). Uburyo bwo gupima burimo gupfunyika firime isukuye neza mumashanyarazi, kuyikuramo mumashanyarazi ya Soxhlet mumasaha 24, hanyuma ukumisha ibisigara bitangirika kuburemere burigihe mbere yo kubara.

2. Imbaraga zifatika:

   Muri kaseti ya Teflon, imbaraga zifatika zirangwa nubushyuhe bwo hejuru bwo gufata imbaraga (ubushyuhe bwo kunanirwa gukonjesha cyangwa gufata igihe). Ikizamini gisanzwe gikorerwa kuri 180 ° C munsi yumutwaro wa kg 1, ukandika igihe kugeza igiti gifatanye cyangwa cyananiranye. Agaciro kagaragaza mu buryo butaziguye ubushobozi bwo gufatira hamwe ubushobozi bwo kurwanya imigendekere no gutandukana.

II. Kwandikirana Kwinshi Hagati ya Gel Igice hamwe nimbaraga zifatika

1. Munsi yingingo zikomeye (agace ka gel <60%):

   Sisitemu itarashiraho umuyoboro wa percolating; igipande gifatika kiguma mumiterere-yimigezi, hamwe nimbaraga zifata zeru kandi nta mbaraga zifatika zifatika.

2. Urwego rufatika (60% –85%):

   Kurenga ingingo ikomeye, ubucucike bukomeye bwa elastique bwiyongera cyane hamwe nigice cya gel, kandi imbaraga zifatika zikura cyane cyangwa gukurikiza amategeko akomeye. Kongera agace ka gel kuva kuri 60% kugeza kuri 70% birashobora kuzamura ubushyuhe bwo hejuru bwo gufata umwanya kuva muminota kugeza kumasaha; kuva 70% kugeza 80%, imbaraga zo gufata zirashobora kwiyongera inshuro 3 kugeza 10. Uburyo bwo kunanirwa buhoro buhoro buva muburyo bunini bwo guhuriza hamwe kunanirwa kuvanze.

3. Urwego rwo hejuru rwuzuzanya (> 85%):

   Ubwiyongere bw'imbaraga zifatika butinda. Kuzamura agace ka gel kuva kuri 85% kugeza kuri 95% byongera igihe cyo gufata 20% - 50% gusa, ariko tack (adhesion yambere) iragabanuka cyane kubera imipaka ya molekile igabanuka. Iyo agace ka gel karenze 95%, igipande gifata cyegereye imiterere ya elastomer, kandi ibintu byangiza-igitutu biratakara.

III. Semi-Empirical Model hamwe namakuru asanzwe

Nkuko byavuzwe muri make na Jiangsu Teflon abakora imyenda yubushyuhe bwo hejuru, isano iri hagati yo gukata igihe (t_shear) nigice cya gel (g) irashobora kugaragazwa nk:

lg (t_shear) = A + B · g (hamwe na B hafi 0.1–0.2), byerekana kwishingikiriza. Indangagaciro za A na B ziterwa nigipimo cya MQ resin, uburebure bwumubyimba, hamwe nubushyuhe bwikizamini.

Ibisobanuro bisanzwe bihuye (180 ° C static shear, bisanzwe mubisanzwe mugihe cyo gufata 1 kuri 65% ya geli):

| Igice cya Gel | Gufata Igihe gifitanye isano | Uburyo bwo Kunanirwa |

| -------------- | ------------------------ | --------------- |

| 55% | <0.1 | Kunanirwa hamwe 100% |

| 65% | 1 | ~ 80% gutsindira hamwe |

| 75% | 8-15 | Kunanirwa kuvanze |

| 85% | 50–100 | Ibisigara bito |

| 92% | 150–200 (hafi yo kwiyuzuzamo) | Kunanirwa hagati yimikorere |

 

Biragaragara ko murwego rwa 60% - 90%, buri gipimo cya 5 ku ijana cyiyongera mubice bya gel bishobora gutuma habaho kwiyongera inshuro nyinshi imbaraga zubushyuhe bwo hejuru.

IV. Ingamba zo kugenzura mubikorwa bya Teflon

1. Intego ya gel igabanijwe:

   Kuri rusange-intego-yubushyuhe irwanya ubushyuhe buturuka kuri Jiangsu Teflon abakora imyenda yubushyuhe bwo hejuru, ibice bya gel bisabwa ni 75% –85%, kuringaniza tack hamwe. Ku bushyuhe bwo hejuru bwo kurwanya imikandara ya convoyeur (hashingiwe ku gupakira igihe kirekire kuri 200-260 ° C), agace ka gel kagomba kugera kuri 85% –93% kugirango hirindwe ibisigazwa bifata biterwa no kugabana hamwe.

2. Imigaragarire ihuza ibisabwa:

   Ubuso bwa PTFE bwa Teflon yubushyuhe bwo hejuru bufite ingufu nkeya cyane; kubwibyo, imbaraga zifatanije zifatika zigomba kuba zisumba imbaraga zifatika zifatika; bitabaye ibyo, kunanirwa gufatanya bizabaho mugihe cyo guhangayika. Niba agace ka gel karenze 93%, igipande gifatika kirakomera, kigabanya guhindagurika no guhuza na substrate ya PTFE, bishobora kuganisha kumutwe. Mu musaruro, ni ngombwa kugenzura neza ubushyuhe bwuzuzanya, igihe, hamwe na catalizator kugirango ufunge agace ka gel mugihe cyagenwe, kugera kuntambwe yizewe kuva kunanirwa guhuriza hamwe kunanirwa hagati.

Amakuru yavuzwe haruguru atangwa na Jiangsu Okai Ibikoresho bishya byikoranabuhanga Co, Ltd.

Niba wifuza kumenya byinshi kubijyanye nibisobanuro birambuye, ibintu bisabwa, hamwe nuburyo bwo kwihitiramo ibicuruzwa byuzuye - harimo imyenda ya Teflon yubushyuhe bwo hejuru, kaseti ya Teflon yubushyuhe bwo hejuru, imikandara ya Teflon yubushyuhe bwo hejuru, imikandara idafite ubudodo bwa laminator, umwenda umwe wa PTFE, wongeyeho ubushyuhe bukabije, feri yubushyuhe bukabije,
