1. Metil / Fenili hakɛ: Baarakɛcogo ladilanni kɔnɔna na kemikɛli sigicogo fɛ

Ka metil kuluw (-CH3) yɔrɔ dɔ bila fenili kuluw (-C6H5) nɔ na, ​​o ye fɛn ye min bɛ se ka fɛn caman sɛmɛntiya molekiyɔmu hakɛ la:

·  Fanga min bɛ bonya molekiyɔmuw ni ɲɔgɔn cɛ : Bɛnzɛni bololanɛgɛ bɛ π-π fɛnɲɛnamafagalanw ni ɲɔgɔn cɛ jɛɲɔgɔnya barikama lase, o bɛ nɔrɔlan ka jɛ fanga kɔrɔta kosɛbɛ, o min bɛ minɛni fanga ni a sɔgɔli fanga ɲɛ kosɛbɛ.

·  Cakɛda molekiyɔmuw gɛlɛyali caya : Fenili kuluw bɛ ni stɛriki balilanba ye, o bɛ silikoni cakɛda kunbabaw jiginni bali ani ka cakɛda sɛgɛsɛgɛli dɔgɔya. O bɛ nafa lase fanga minɛni ma nka a ka teli ka daminɛ tack barika dɔgɔya.

·  Jisigicogo ɲuman : Fenili caman cili bɛ silikoni PSA ka ɲɔgɔndɛmɛ bonya ni substrat surfaces ye, ka ɲɔgɔn cɛ jɛɲɔgɔnya sabati, ani ka tack fɔlɔ ni peel fanga bɛɛ ɲɛ.

2. Molecules Weight & Distribution: Baarakɛcogo ɲɛnabɔli ni farikoloɲɛnajɛ ni ɲɔgɔn cɛ cogoya ye

Baarakɛjɛkuluw bɛ fanga sɔrɔ kemikaliya labɛnni na , ka sɔrɔ molekiyɔmu girinya ni molekiyɔmu girinya tilali (Polydispersity Index, PDI) bɛ fanga sɔrɔ farikolo labɛnni na :

Molekuli girinya (Mw) .

Jɛɲɔgɔnya fanga bɛ Bɔ kɛrɛnkɛrɛnnenya la polimɛri cakɛdaw farikolo-ɲɛnajɛ la.

·  Mw min ka bon, o bɛ kɛ sababu ye ka entanglement network (rezo) min ka bon kosɛbɛ, wa a bɛ fanga minɛcogo ɲɛ kosɛbɛ.

·  Mw ka ca kojugu, o bɛ cakɛdaw kɛ molekiyɔmuw ye minnu bɛ gɛlɛya ani minnu tɛ se ka wuli kosɛbɛ, o bɛ na ni tack ni peel fanga daminɛ na dɔgɔya.

Molecules girinya tilatilali (MWD) .

·  Jatebɔ fitinin : Baara kɛcogo kelen, laɲini nɔgɔyalen ɲɛnabɔli la nafolo kelen kama i n’a fɔ tack fɔlɔ sanfɛ.

·  Jatebɔba : Baarakɛcogo bɛnkan dafalen. Fɛnɲɛnɛma-yɔrɔw minnu girinya ka bon, olu bɛ kɛ rezo koloma gɛlɛn ye walasa ka jɛɲɔgɔnya fanga ni minɛ fanga garanti; fɛn minnu girinya ka dɔgɔn, olu bɛ kɛ i n’a fɔ kɔnɔna tulumafɛnw ani jisigi teliyalanw, ka cakɛda lamagacogo ɲɛ ani ka dugukolo ɲigin teliya la walasa ka daminɛ tack ɲuman sɔrɔ, ka baara kɛcogo bɛɛ lajɛlen balannen sɔrɔ.

3. M/Q Ratio, Resin Dosage ani Silicone Rubber Viscosity ka ɲɛtaa ɲuman kɛ ɲɔgɔn fɛ

Metil/fenili hakɛ ni molekiyɔmu girinya bɛ MQ resin ka jogo danmadɔw dantigɛ; k’a sɔrɔ M/Q hakɛ, resin ni silikɔni lastikuw hakɛ ani silikɔni lastikuw sɔgɔli ye ladilanni tilennenw ye formula injiniyɛri la, minnu ka kan ka bɛn ɲɔgɔn ma.

M/Q Ratiyo ye

M/Q hakɛ bɛ molekiyɔmu girinya, hidrɔkisili hakɛ ani a ni silikoni lastikuw bɛnkan jira k’a ɲɛsin ɲɔgɔn ma.M/Q molari hakɛ ɲuman silikoni PSA la, a ka c’a la, o ye 0,6 ~ 1,2 ye .Misali la, furakɛli-kalan PSA bɛ M/Q hakɛ ɲuman ta min bɛ se 0,78 ɲɔgɔn ma resin ni M/Q 0,6–0,9 faralen ɲɔgɔn kan ni silikoni lastikuw ye (a sɔgɔli 100×10−4 m²/s) ni a girinya hakɛ ye 2:3 ye, o bɛ nɔrɔli baarakɛcogo ɲumanba sɔrɔ.

Resin / Silicone Lastikuw ɲagaminen hakɛ

O hakɛ in ye fɛnba ye min bɛ se ka kɛ sababu ye ka fɛn saba kolomaw (tack fɔlɔ, minɛ fanga, peel fanga) balansi.

·  Resin hakɛ cayalenba bɛ jɛɲɔgɔnya sabati, ka fanga minɛ ani ka ɲɛgɛnw fanga bonya nka a bɛ dɔ bɔ tack fɔlɔ la.

·  Lastikuw hakɛ cayalenba bɛ a kɔfɛko jira.

Misali la, ni aw ye MQ resin girinya hakɛ kɔrɔta ka se silikɔni lastikuw 107 ma ka bɔ 1,2 na ka se 2,5 ma, o bɛna dɔ fara minɛ fanga kan ani 180° sɔgɔli fanga kan ka sɔrɔ ka dɔ bɔ a daminɛ na tack.Furakɛcogo waleyali la, silikoni resin ni silikɔni lastikuw girinya hakɛ ka teli ka kɛ 45:55 ~ 75:25 ye.

Silikoni Lastikuw ka Viscosité

Molecules girinya min bɛ jira ni viscosité ye, o de bɛ adhesive system ka rheological jogo jɔnjɔnw dantigɛ, wa a mago bɛ bɛnkan ɲuman na ni MQ resin ye.Silicone rubber min ka viscosity ka dɔgɔn, o bɛ bɛn MQ resin ma ka ɲɛ, a ka ɲi tack fɔlɔ ni peel fanga ma, nka a bɛ se ka minɛ fanga tiɲɛ.

4. Formula dilancogo sariyasun min bɛ baarakɛcogo balansi kan

Silikoni PSA furakɛlicogo la, index kunbaba saba — tack fɔlɔ, minɛ fanga, 180° peel fanga  — bɛ se ka labɛn tigitigi ni core fɛɛrɛ fila ye:

·  Fenyl modification — multiplicative optimization : Fenili doping ɲuman bɛ jogo saba bɛɛ ɲɛ waati kelen na, ka laadala seesaw dantigɛli tiɲɛ.

·  Molecular weight & distribution adjustment — additive trade-off : Molecular weight ni distribution kɔlɔsili tigitigi bɛ balansi customized kɛ tack fɔlɔ ni holding power cɛ application scenarios wɛrɛw kama.

Industriw ka baarakɛcogo la, formula kɛcogo min bɛ kɛ tuma bɛɛ, o ye basigi resin ye min ka bon ni fenili girinya tilali ye ka fara fenili caman caman cili kan  walasa ka baarakɛcogo ni nɔrɔli baarakɛcogo bɛɛ lajɛlen balansi.For ultra-high temperature resistance and harsh chemical environments, high-phenyl-content MQ resin is the preferred solution.
