Ke mangolo afe a mangata pakeng tsa index ea karolo ea gel ea li-adhesives tse nang le khatello ea silicone le matla a kopantsoeng a lera la sekhomaretsi?

I. Tlhaloso le Tekanyo ea Mekhoa ea Lipontšo

1. Karolo ea gel:

   Karolo ea gel e bolela karolo ea bongata ba marang-rang a marang-rang a sekhomaretsi sa silicone se nang le khatello ea kelello se koahetsoeng. Theipi ea Teflon e nang le mocheso o phahameng oa mocheso e sa keneng ka har'a li-solvents tse ntle (joaloka toluene). Mokhoa oa ho lekanya o kenyelletsa ho phuthela filimi e hloekileng ea sekhomaretsi ka har'a letlooeng la filthara, ho e ntša ka mochine oa Soxhlet ka lihora tse 24, ebe o omisa masala a sa tsitsang ho boima bo sa khaotseng pele ho bala.

2. Matla a momahaneng:

   Ka tepi ea Teflon, matla a momahaneng a tšoauoa ka matla a ho tšoara mocheso o phahameng (mocheso oa ho hloleha ha ho kuta kapa ho tšoara nako ea ho kuta). Teko e atisa ho etsoa ka 180 ° C tlas'a mojaro oa 1 kg, ho rekota nako ho fihlela lesela la sekhomaretsi le thella kapa le hlōleha. Boleng bona bo bonahatsa ka ho toba bokhoni ba lera la sekhomaretsi ho hanela phallo le ho petsoha.

II. Bongata ba Lingollano Pakeng tsa Gel Fraction le Cohesive Strength

1. Ka tlase ho ntlha ea bohlokoa (karolo ea gel <60%):

   Tsamaiso ha e e-s'o thehe marang-rang a percolating; sekhomaretsi sa sekhomaretsi se lula se le boemong ba ho phalla ha viscous, se nang le matla a ho tšoara a atamela zero 'me ha ho na matla a sebetsang a momahaneng.

2. Mefuta e sebetsang (60%–85%):

   Ka nģ'ane ho ntlha e mahlonoko, sekhahla se sebetsang sa ketane ea elastic se eketseha haholo ka karoloana ea gel, 'me matla a momahano a hōla ka potlako kapa a latela molao oa matla a phahameng. Ho eketsa karolo ea gel ho tloha ho 60% ho ea ho 70% ho ka phahamisa nako ea ho tšoara mocheso o phahameng ho tloha metsotso ho ea ho lihora; ho tloha ho 70% ho isa ho 80%, matla a ho tšoara a ka eketseha ka makhetlo a 3 ho isa ho a 10. Boemo ba ho hloleha butle-butle bo fetoha ho tloha ho hloleha ho hoholo ha momahano ho ea ho ho hloleha ho kopaneng.

3. Likamano tse phahameng tsa marang-rang (> 85%):

   Ho eketseha ha matla a momahano ho fokotseha. Ho phahamisa karoloana ea gel ho tloha ho 85% ho ea ho 95% ho eketsa nako ea ho tšoara ka 20% -50% feela, empa tack (ho khomarela qalong) e theoha haholo ka lebaka la ho thibela ho tsamaea ha molek'hule. Ha karolo ea gel e feta 95%, lera la sekhomaretsi le atamela boemo bo hloekileng ba elastomer, 'me thepa ea sekhomaretsi e mamellang khatello e hlile e lahlehile.

III. Semi-Empirical Model le Boitsebiso bo Tlwaelehileng

Joalo ka ha ho akaretsoe ka baetsi ba masela a mocheso o phahameng oa Jiangsu Teflon, kamano e matla lipakeng tsa nako ea ho kuta (t_shear) le karolo ea gel (g) e ka hlalosoa ka tsela e latelang:

lg(t_shear) = A + B · g (ka B hoo e ka bang 0.1–0.2), e bontšang ho itšetleha ka matla. Maemo a A le B a ipapisitse le karo-karolelano ea resin ea MQ, botenya ba sekhomaretsi, le mocheso oa liteko.

Lintlha tse lumellanang le tsona (180 °C static shear, e tloaelehileng ho nako ea 1 ho karolo ea 65% ea gel):

| Karolo ea Gel | Relative Holding Time | Mokhoa oa ho hloleha |

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

| 55% | <0.1 | 100% ho hloleha ho kopaneng |

| 65% | 1 | ~ 80% ho hloleha ho kopaneng |

| 75% | 8–15 | Ho hloleha ho kopaneng |

| 85% | 50–100 | Masala a manyane |

| 92% | 150–200 (haufi le saturation) | Ho hloleha ha sefahleho se hloekileng |

 

Ho totobetse hore karolong ea 60% -90%, keketseho e 'ngoe le e' ngoe ea karolo ea 5 lekholong ea karoloana ea gel e ka lebisa ho eketseha ka makhetlo a mangata ho matla a ho kopanya a phahameng a mocheso.

IV. Laola Maano a Teflon Tape Manufacturing

1. Lenane la likaroloana tsa gel:

   Bakeng sa litheipi tse tsoelipanang tse thibelang mocheso ka kakaretso tse tsoang ho baetsi ba masela a mocheso o phahameng oa Jiangsu Teflon, karolo e khothaletsoang ea lijeli ke 75%–85%, ho leka-lekanya ho sebetsa le momahano. Bakeng sa mabanta a conveyor a phahameng a mocheso a khahlanong le lithupa (ho itšetlehile ka ho jara nako e telele ho 200-260 ° C), karolo ea gel e tlameha ho fihla ho 85% -93% ho thibela masala a sekhomaretsi a bakoang ke ho arohana ho hokahaneng ha lera la sekhomaretsi.

2. Litlhoko tse tsamaellanang le li-interface:

   The PTFE holim'a Teflon phahameng-thempereichara theipi na le tlaase haholo holim'a matla a matla; ka hona, matla a kopantsoeng a lera la sekhomaretsi e tlameha ho ba holimo ho feta matla a ho kopanya sefahleho; ho seng joalo, ho hlōleha ho kopane ho tla etsahala tlas'a khatello ea kelello. Haeba karoloana ea gel e feta 93%, lera la sekhomaretsi le fetoha le thata, le fokotsa ho koloba le ho lumellana le karoloana ea PTFE, e ka lebisang ho phahamisa bohale. Ha ho etsoa tlhahiso, ho bohlokoa ho laola ka nepo mocheso o kopanyang, nako, le tekanyo ea li-catalyst ho notlela karoloana ea li-gel ka har'a sepheo sa sepheo, ho fihlela phetoho e tšepahalang ho tloha ho hloleha ho kopaneng ho ea ho ho se atlehe ha sefahleho.

Lintlha tse ka holimo li fanoe ke Jiangsu Okai New Material Technology Co., Ltd.

Haeba u ka rata ho ithuta haholoanyane ka litlhaloso tse qaqileng, maemo a ts'ebeliso, le likhetho tsa ho iketsetsa lihlahisoa tsa rona tse feletseng-ho kenyeletsoa lesela la Teflon le mocheso o phahameng oa mocheso, litheipi tsa Teflon tse nang le mocheso o phahameng oa mocheso, mabanta a marang-rang a Teflon, mabanta a se nang seamless bakeng sa laminators, lesela le le leng le nang le mahlakoreng a mabeli, lesela le lengata, masela a fiberglass a phahameng a mocheso, le tse ling-ka kopo ikutloe u lokolohile ho ikopanya le rona ka tse latelang:
