Bedelka hawada (hadda ka dib waxaa loo yaqaan "hawo wareejinta", halkan waxaan si gaar ah u tixraacnaa GB10963.1 heerka caadiga ah ee wareegga guriga) walaxda ilaalinta inta badan waa fiilada, su'aasha ugu weyni waa "maxay tahay sababta dabaysha hawadu u dejiso ilaalinta xad-dhaafka ah iyo ilaalinta wareegga gaaban" waxaa lagu kordhin karaa "maxay tahay sababta fiilada loo dejiyo ilaalinta culeyska xad dhaafka ah iyo ilaalinta wareegga gaaban isku mar"
1.Waa maxay xad dhaafka?
Wareegga hadda socda ee ka weyn kan la qiimeeyay ee qaadaya wareegtada ayaa ah mid xad dhaaf ah, oo ay ku jiraan culeyska xad dhaafka ah ee hadda iyo hadda wareega gaaban.
2. ilaalinta xad dhaafka fiilada
Wareegga korantada oo ay ugu wacan tahay qalabka korantada oo aad u badan ama qalabka korantada laftiisa culeyska xad dhaafka ah (sida culeyska mashiinka mashiinka ayaa aad u weyn) iyo sababo kale, qiimaha hadda jira marar badan ayaa la qiimeeyay wareegga wareegga, natiijadu waa in heerkulka hawlgalka fiilada uu dhaafo. Qiimaha la oggol yahay, dahaarka fiilada ayaa dedejiyey xumaanta, soo gaabin nolosha.Tusaale ahaan, fiilooyinka PVC, heerkulka ugu badnaan ee la oggol yahay ee shaqada muddo dheer waa 70 ° C, heerkulka ku-meel-gaarka ah ee la oggol yahay haddii uu jiro wareegga gaaban kama badna 160 ° C.
Fiilada ayaa u adkeysan karta xad xad dhaaf ah oo hadda socda muddo cayiman, laakiin muddada waa in la xaddidaa.Haddii culeyska xad dhaafka ah uu sii dheeraado, daboolka fiilada ayaa dhaawacmi doona, taasoo aakhirka sababi karta cilad wareeg gaaban.Xaaladda heerkulka lakabka dahaarka ee fiilada ee hoos yimaada hadda caadiga ah, culeyska xad dhaafka ah, iyo hadda wareegga gaaban.
Sidaa darteed, qiimaha caadiga ah ee badeecada wareegga wareegga, xiraha wareegga waxaa looga baahan yahay inuu ahaado 1.13In, culeyska xad-dhaafka ah ma shaqeynayo 1 saac gudahood (In≤63A}), iyo marka hadda la furo 1.45In, culeyska xad-dhaafka ah khadka waa in laga saaraa 1 saac gudahood.Xakamaynta xad-dhaafka ah ee hadda jirta ayaa loo oggol yahay inay sii socoto 1 saac si loo tixgeliyo sii wadida korontada iyo fiilada lafteeda ayaa leh awood xad dhaaf ah, ma noqon karto wax yar oo xad dhaaf ah, xadhkaha wareegga ayaa jaraya korontada, taas oo saameyn doonta caadiga ah. wax soo saarka iyo nolosha dadka deegaanka.
Shayga ilaalinta ee fiilada wareegga waa fiilada.Xaaladaha culeyska xad-dhaafka ah, culeyska muddada-dheer waxay keeni doontaa in heerkulku kor u kaco, taasoo keentay dhaawac soo gaara lakabka dahaadhka ee fiilada, iyo ugu dambeyntii cillad wareeg gaaban.
Xaaladaha wareegga gaaban, heerkulku wuxuu kici doonaa waqti aad u gaaban, haddii aan la gooyn, waxay keeni kartaa gubasho lama filaan ah lakabka dahaarka, sidaas darteed qayb ka mid ah ilaalinta wareegga wareegga, labadaba ilaalinta xad-dhaafka ah, laakiin sidoo kale waxay u baahan yihiin gaaban. shaqada ilaalinta wareegga.
