A: Baldhinta silsiladdu waxay tahay habka wax soo saarka ee aasaasiga ah ee xabagta tayada sare leh (automotive/warshadaha). Waxay gaartaa qaab gebi ahaanba ah oo xabagta ah oo leh goobo goobo oo go'an iyada oo loo marayo quudinta joogtada ah → qaabeynta baldhin → vulcanization online → ka shaqeynta kadib. Faa'iidada ugu muhiimsan ayaa ah inay xaqiijiso joogtaynta xabagta baldhinaha oo aad u sarreeya (khaladka goobo ≤±0.1mm), hanti jireed oo deggan, iyo taageerada soo saarista mass-ka 24-saac—taasi waa sababta ay doorashada ugu horreysa u tahay taageerada OEM ee qaybaha xabagta ee baabuurta iyo warshadaha.

A: Xaaladaha heerkulka aadka u sarreeya (foornada warshadaha, qaybaha mashiinada, tuubooyinka kiimikada heerkul sare leh), xulashada agabka waxay ku saleysan tahay heerkulka dhabta ah ee la arko:

• 150-180℃: EPDM ka xasaasi ah heerkul sarreeya (qiimo jaban, aasaas ahaan ka-hortagga da'da kulaylka);
• 150-200℃: FVMQ (caag fluorosilicone, iska caabin cimilada oo fiican + iska caabin heerkul sare);
• 200-300℃: FFKM (perfluoroelastomer, oo ah caag-heerar sare leh, iska caabbinta heerkulka ugu fiican ee alaabooyinka caaga, xaaladaha heerkulka aadka u sarreeya).

Intaas waxaa dheer, qaab-dhismeedka xariijinta caaga ah waxaa lagu talinayaa inuu isticmaalo naqshad dhaawac yar, iyadoo la kordhinayo dhumucda ku habboon iyo buuxinta kuleylka gudaha si kor loogu qaado u adkeysiga heerkul sare.

A: Astaamaha asaasiga ah ee jireed ee si toos ah u go'aamiya natiijada isticmaalka caaradaha/qalabka xidhista ayaa ah 4 shay oo fur ah, iyadoo shuruudaha heerka warshadaha ay yihiin sida soo socota:

1. Adkeysi: 40-70 Shore A (55-65 Shore A loogu talagalay laamiyada gaadiidka, laga hagaajin karo shuruudaha shaqada ee laamiyada warshadeed);
2. Xoogga Xirashada: ≥8MPa (waxyaabaha HNBR ee waxqabadka sare ≥15MPa);
3. Dhererka Jabinta: ≥300% (hubi adkeysiga iyo ka-hortagga jebinta);
4. Xirmada Daji: ≤25% (70℃×22h, 150℃×70h oo loogu talagalay agabyada heerkulka sare—tilmaame muhiim ah oo muujinaya nolosha xidhidha).

Dhammaan tilmaamayaasha ayaa la tijaabiyaa iyadoo loo raacayo heerarka caalamiga ah ee ISO, iyadoo la raacayo xakameyn khalad oo adag (tusaale, qalad adag ≤±2 Shore A).
