Saliid garaaso
Waxyaabaha lagu daro canaafacadaha badan ee lagu daro warshadaha PVC
| Saliidaha gudaha ee TP-60 | |
| Cucid | 0.86-0.89 G / cm3 |
| Tilmaanta tabaruca (80 ℃) | 1.453-1.463 |
| Viscosity (MPA.S, 80 ℃) | 10-16 |
| Qiimaha acid (mgkoh / g) | 10 |
| Qiimaha Iodine (GL2 / 100G) | <1 |
Saliidaha gudaha waa waxyaabo muhiim ah oo lagu daro ka baaraandegidda PVC, maadaama ay door muhiim ah ka ciyaaraan yareynta xoogagga isle'egga ee u dhexeeya silsiladaha PVC, taasoo dhalisay jaceylka hoose. Ahaanshaha dabeecadda dabiiciga ah, waxay ku soo bandhigaan is-waafajinta sare ee PVC, hubinta in fidsan wax ku oolka ah inta lagu jiro maaddada.
Mid ka mid ah faa'iidooyinka caanka ah ee saliidaha gudaha waa awood ay ku leeyihiin inay ku noolaadaan daahfurnaan aad u wanaagsan xitaa qiyaasta sare. Fannaantaani waa mid aad loo jecel yahay codsiyada ay cadeyntu muuqata ay muhiim u tahay, sida agabyada baakadaha hufan ee hufan ama muraayadaha indhaha.
Faa'iido kale ayaa ah in saliidaha gudaha aan u muuqan inay fajacaan ama u haajiraan dusha sare ee badeecada PVC. Hantikan aan caqliga lahayn wuxuu hubiyaa alxanka la wanaajiyo, gladaha, iyo daabacaadda astaamaha sheyga ugu dambeeya. Waxay ka hortagtaa dusha sare ee ubaxyada waxayna haysaa daacadnimada maaddada, hubinta waxqabadka joogtada ah iyo suuxinta.
| Saliidaha dibedda ee tp-75 | |
| Cucid | 0.88-0.93 G / cm3 |
| Tilmaanta tabaruca (80 ℃) | 1.42-1.47 |
| Viscosity (MPA.S, 80 ℃) | 40-80 |
| Qiimaha acid (mgkoh / g) | 12 |
| Qiimaha Iodine (GL2 / 100G) | <2 |
Saliidayaasha dibedda waa wax lagu daro waxyaabaha lagu daro ee ku saabsan howsha PVC, maadaama ay door muhiim ah ka ciyaaraan yareynta kudhaca kudhaca PVC iyo sagxadaha birta. Saarbanjiifkan ayaa inta badan aan ahayn kuwa aan dabiici ahayn ee dabiiciga ah, oo leh paraffin iyo wax lagu cuno paraffin iyo polyetyylen ah oo loo isticmaalo tusaalooyin caadi ah. Waxtarka ee linerifka dibedda ah ayaa inta badan waxay kuxirantahay dhererka silsilada hydrocarbon, giraangirihiisa, iyo jiritaanka kooxaha shaqeeya.
In kasta oo saliidaha dibedda ay faa'iido u leeyihiin in la ilaaliyo xaaladaha ka baaraandegista, qiyaasta ayaa loo baahan yahay in si taxaddar leh loo xakameeyo. Qiyaasta sare, waxay u horseedi karaan waxyeelo aan loo baahnayn sida daruuro ah sheyga ugu dambeeya iyo saliidaha saliidaha dusha sare. Markaa, helitaanka isku dheelitirka saxda ah codsigooda ayaa muhiim ah si loo hubiyo in labaduba ay hagaajinayaan iyo in la doonayo in wax soo saarka wax soo saarka la doonayo.
Iyaga oo yareynaya kudhaca u dhexeeya PVC iyo sagxadaha birta, saliidaha dibedda ee fududeynta ka-hortagga ka-hortagga iyo ka hortagga maaddada inay ku dhegaan qalabka. Tani waxay kor u qaadeysaa hufnaanta hanaanka wax soo saarka waxayna gacan ka geysaneysaa joogtaynta sharafta sheyga ugu dambeeya.
