Kodi pali kulumikizana kotani pakati pa zomatira zomata za silikoni ndi mphamvu yolumikizana ya zomatira?

I. Tanthauzo ndi Njira Zoyezera za Zizindikiro

1. Gawo la Gel:

   Gawo la gelsi limatanthawuza kuchuluka kwa maukonde olumikizidwa mu zomatira zomwe zimakutidwa ndi silikoni. Teflon high-temperature tepi yomwe ili yosasungunuka mu zosungunulira zabwino (monga toluene). Njira yoyezera imaphatikizapo kukulunga filimu yoyera yomatira mu mesh ya fyuluta, kuichotsa mu Soxhlet extractor kwa maola 24, ndiyeno kuyanika zotsalira zosasungunuka kuti zikhale zolemera nthawi zonse musanawerenge.

2. Mphamvu zogwirizana:

   Mu tepi ya Teflon, mphamvu yogwirizana imadziwika ndi mphamvu yogwira kutentha kwambiri (kumeta ubweya wa ubweya wa ubweya kapena nthawi yogwira ntchito). Kuyesako kumachitika pa 180 ° C pansi pa katundu wa 1 kg, kujambula nthawiyo mpaka chomata chitsetsereka kapena kulephera. Mtengo uwu umawonetsa mwachindunji mphamvu ya zomatira zomwe zimatha kukana kuyenda ndi kugawanika.

II. Kulumikizana Kwambiri Pakati pa Chigawo cha Gel ndi Mphamvu Yogwirizana

1. Pansi pa mfundo yofunika kwambiri (gawo la gel <60%):

   Dongosolo silinakhazikitsebe network ya percolating; wosanjikiza zomatira amakhalabe mu mawonekedwe a viscous-flow, ndi mphamvu yogwira ikuyandikira zero ndipo palibe mphamvu yogwirizana.

2. Zothandiza (60%–85%):

   Kupitilira pa mfundo yofunika kwambiri, kachulukidwe ka unyolo kogwira mtima kumawonjezeka kwambiri ndi gawo la gel, ndipo mphamvu yolumikizana imakula mwachangu kapena kutsatira lamulo lamphamvu kwambiri. Kuchulukitsa gawo la gel kuchokera ku 60% mpaka 70% kumatha kukweza nthawi yogwira kutentha kwambiri kuyambira mphindi mpaka maola; kuchokera 70% mpaka 80%, mphamvu yogwira imatha kuwonjezeka ndi zina 3 mpaka 10. Njira yolephereka pang'onopang'ono imasintha kuchoka ku kulephera kogwirizana mpaka kulephera kosakanikirana.

3. Kulumikizana kwakukulu (> 85%):

   Kuwonjezeka kwa mphamvu zogwirizanitsa kumachepetsa. Kukweza kagawo ka gel osakaniza kuchokera ku 85% mpaka 95% kumawonjezera nthawi yogwira ndi 20% -50% yokha, koma tack (kumatira koyamba) kumatsika kwambiri chifukwa cha kuchepa kwa ma chain chain. Gawo la gel likadutsa 95%, zomatira zimafika pamtundu wa elastomer yoyera, ndipo zomatira zosagwirizana ndi kukakamiza zimatayika.

III. Semi-Empirical Model ndi Typical Data

Monga tafotokozera mwachidule opanga nsalu za Jiangsu Teflon zotentha kwambiri, ubale wamphamvu pakati pa nthawi yometa ubweya wa ubweya (t_shear) ndi gawo la gel (g) ukhoza kufotokozedwa motere:

lg(t_shear) = A + B · g (ndi B pafupifupi 0.1–0.2), kusonyeza kudalira kwambiri. Makhalidwe a A ndi B amadalira kuchuluka kwa utomoni wa MQ, makulidwe a zomatira, ndi kutentha kwa mayeso.

Zambiri zofananira (180 °C static shear, yokhazikika mpaka nthawi yogwira 1 pa 65% kagawo ka gel):

| | Chigawo cha Gel | Nthawi Yogwira Mwachibale | Kulephera Mode |

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

| | 55% | <0.1 | 100% kulephera kogwirizana |

| | 65% | 1 | ~ 80% kulephera kogwirizana |

| | 75% | 8-15 | Kulephera kosakanikirana |

| | 85% | 50-100 | Zotsalira pang'ono |

| | 92% | 150-200 (pafupi ndi machulukitsidwe) | Kulephera kofananako |

 

Zikuwonekeratu kuti mumtundu wa 60% -90%, kuwonjezeka kwa 5 peresenti mu gawo la gel kungapangitse kuwonjezereka kowonjezereka kwa mphamvu zogwirizanitsa kutentha.

IV. Njira Zowongolera mu Teflon Tape Manufacturing

1. Gulu la magawo a gel omwe mukufuna:

   Kwa matepi okhotakhota osagwira kutentha kwanthawi zonse ochokera kwa opanga nsalu zotentha kwambiri za Jiangsu Teflon, kagawo ka gelisi kovomerezeka ndi 75% -85%, kusanja tack ndi kulumikizana. Kwa malamba okwera kwambiri oletsa ndodo (malinga ndi kukweza kwa nthawi yayitali pa 200-260 ° C), kachigawo ka gel kakuyenera kufika 85% -93% kuti ateteze zotsalira zomatira zomwe zimayambitsidwa ndi kugawanika kwa zomatira.

2. Zofunikira zofananira ndi mawonekedwe:

   The PTFE pamwamba Teflon mkulu-kutentha tepi ali otsika kwambiri pamwamba mphamvu; Choncho, mphamvu yogwirizana ya zomatira wosanjikiza ayenera kukhala apamwamba kuposa interfacial adhesion mphamvu; mwinamwake, kulephera kogwirizana kudzachitika pansi pa kupsinjika maganizo. Ngati kachigawo ka gel osakaniza kuposa 93%, wosanjikiza zomatira amakhala olimba, kuchepetsa kunyowetsa ndi conformability kwa gawo lapansi PTFE, zomwe zingachititse kukweza m'mphepete. Popanga, ndikofunikira kuwongolera bwino kutentha kwapang'onopang'ono, nthawi, ndi mlingo wothandizira kuti mutseke kagawo ka gelisi mkati mwazomwe mukufuna, kuti pakhale kusintha kodalirika kuchokera pakulephera kolumikizana mpaka kulephera kwa mawonekedwe.

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Okai New Material Technology Co., Ltd.

Ngati mukufuna kudziwa zambiri zatsatanetsatane, mawonekedwe ogwiritsira ntchito, ndi zosankha zomwe mungasinthire pazogulitsa zathu zonse-kuphatikiza nsalu za Teflon zotentha kwambiri, matepi otentha kwambiri a Teflon, malamba amtundu wa Teflon, malamba opanda zomatira opanda zomatira a laminators, single-sided, consveder-FE nsalu za fiberglass zotentha kwambiri, ndi zina zambiri-chonde omasuka kulumikizana nafe kudzera mu izi:

Imbani foni yathu yothandizira:

- Bambo Guo: 18944819998

- Bambo Liu: 13705266308

Nthawi zonse timatsatira malingaliro aukadaulo komanso umphumphu wautumiki, ndipo tadzipereka kukupatsirani mayankho okhazikika komanso ntchito yachidwi!
