Iisealants zePolyurethane vs. iSilicone: Yeyiphi Efanelekileyo Kuwe?

Ukukhetha isitywini esifanelekileyo sesinye sezona zigqibo zibalulekileyo ezichaphazela ukusebenza kwexesha elide kweprojekthi zokwakha, ukuhlanganiswa kwemizi-mveliso, kunye nobunjineli befaçade. Izitywini zinempembelelo ngqo:

  • --Ukuqina kwamalungu

  • --Ukuqina kwamanzi nomoya

  • --Ukhuseleko lwesakhiwo

  • --Umgangatho wobuhle

  • --Imijikelo yolondolozo

Njengomvelisi wehlabathi ogxile kwiizinto zokuvala i-silicone, izitywini ze-polyurethane (PU), Iinkqubo zokuncamathelisa ze-PUkunyeizisombululo zokuthintela amanzi ukwakhiwa, ISiwayibonelela ngamachiza kwaye iyaqonda amandla kunye nemida yawo kwiisayensi yezinto eziphathekayo, ubunjinelikunyeesekelwe kwisiceloumbono.

Esi sikhokelo sibonelelauthelekiso olupheleleyo nolunegunyaye-PU vs. i-silicone—exhaswa yiIindlela zovavanyo lwe-ASTM/ISO, imigaqo yovavanyo lwelabhoratrikunyeulwazi lwesicelo sehlabathi lokwenyanikwimveliso kaSiway kunye namava abathengi.

1. I-Material Chemistry kunye nokuziphatha kwesakhiwo

1.1 Ii-Polyurethane Sealants (i-Organic Polymer Chemistry)

Ii-polyurethane sealants (PU) zisekelwe kwimpendulo phakathi kwee-polyols kunye nee-isocyanates, zenze i-i-elastomer yendalo edibeneyoOlu lwakhiwo lunika ii-sealants ze-PU:

Izitywini zePolyurethane (iKhemistri yePolymer yendalo)

  • --Ukumelana neenyembezi okuphezulu

  • --Ukunamathela okuqinileyo kwiziseko ezinamagqabi

  • --Ukumelana nokukrala okuphezulu

  • --Intsebenzo entle kakhulu yoomatshini

Izitywini ze-PU zenza iibhondi ze-elastomeric ezihlala ixesha elide ezifanelekileyo kwezi:

  • --Iijoyinti zekhonkrithi

  • --Amalungu okushukuma kwesakhiwo

  • --Indibano yemizi-mveliso

  • --Umgangatho onzima

  • --Ukuvalwa kweperimeter ngoxinzelelo loomatshini

Umqolo wazo wendalo uzenza zibe sesichengeni sokuwohloka kwe-UV ixesha elide ngaphandle kokuba zilungiswe ngokukodwa—yingakho iimveliso ze-PU zodidi oluphezulu zifunaIziqinisi ze-UV, ii-antioxidantskunyeukuhambelana kokukhusela okukhuselekileyo.

1.2 Izitywini zeSilicone (iKhemistri yePolymer engaphiliyo)

Izitywini zesilicone zisekelwe kwiimixokelelwane ye-polysiloxane (Si–O–Si), umqolo ongaphiliyo obonelela ngokungalinganiyo:

Izitywini zeSilicone (iKhemistri yePolymer engaphiliyo)

  • --Uzinzo lwe-UV

  • --Uzinzo lobushushu
