Xidhiidhiyaha Dheddigga ee PVC oo si Buuxda u Dahaaran
Xidhiidhiyayaasha dheddigga ah ee FDFD oo si buuxda u dahaaran waxaa laga sameeyay naxaas tayo sare leh, oo ah walxo loo yaqaan hufnaanteeda iyo cimri dhererkeeda. Xidhiidhiyayaasha naxaasta ah waxaa warshaduhu u doorbidaan iska caabbinta daxalka iyo awoodda ay u leeyihiin inay sii wadaan xiriir deggan waqti ka dib. Astaantan ayaa si gaar ah muhiim ugu ah deegaannada ay qoyaanka iyo walxaha kale ee daxalka ahi ku jiri karaan. Iyadoo la adeegsanayo naxaasta taxanaha FDFD, Gao Peng wuxuu hubinayaa in isticmaalayaashu ay ku tiirsanaan karaan isku xirayaashan si ay u helaan waxqabad waara, taasoo yaraynaysa baahida loo qabo beddelka iyo dayactirka joogtada ah.
Dahaarka waa qayb muhiim ah oo ka mid ah isku xiraha korontada, Xiriiriyayaasha FDFD ee Dumarka oo si Buuxda u Dahaarka lehna way ku fiican yihiin arrintan. Isku xire kasta waxaa lagu duubay lakab dahaarka PVC ah, kaas oo bixiya ilaalin dheeraad ah oo ka dhan ah gaagaaban korontada iyo taabashada shilalka ah. Dahaarkani ma aha oo kaliya inuu hagaajiyo badbaadada, laakiin sidoo kale wuxuu kordhiyaa waxtarka guud ee nidaamka korontada isagoo yareynaya luminta tamarta. Naqshadeynta si buuxda u dahaarka leh ee isku xiraha FDFD waxay hubineysaa in isticmaalayaashu ay si kalsooni leh u shaqeyn karaan, iyagoo og in xiriirkoodu uu ammaan yahay oo uusan saameyn doonin arrimo dibadda ah.
Kala duwanaanta isku xirayaasha FDFD ee si buuxda u dahaaran ayaa ka dhigaysa kuwo ku habboon codsiyo kala duwan. Hadday yihiin baabuurta, warshadaha ama qalabka elektaroonigga ah ee macaamiisha, isku xirayaashan waxaa loo isticmaali karaa in lagu abuuro isku xiryo koronto oo la isku halleyn karo oo hufan. Moodooyinka kala duwan ee taxanaha FDFD waxay daboolaan cabbirro kala duwan oo fiilooyin ah iyo shuruudaha isku xirka, taasoo u oggolaanaysa isticmaalayaasha inay doortaan ikhtiyaarka ugu habboon baahiyahooda gaarka ah. La qabsigan waa faa'iido weyn oo loogu talagalay injineerada iyo farsamoyaqaannada u baahan xalal la isku halleyn karo si ay u dhammaystiraan mashaariic kala duwan.
Xidhiidhiyaha FDFD ee dheddigga ah ee Gaopeng wuxuu matalaa horumar weyn oo ku yimid tignoolajiyada isku xirka korontada. Iyada oo leh dhismaheeda naxaasta ah ee adag iyo dahaarka PVC ee la isku halleyn karo, isku xidhaha waxaa loogu talagalay inuu bixiyo waxqabad iyo badbaado ugu wanaagsan codsiyada kala duwan. Taxanaha FDFD waxaa ka mid ah moodooyinka FDFD1.25, FDFD2 iyo FDFD5.5, kuwaas oo ah qayb muhiim u ah xirfadlayaasha warshadaha korontada sababtoo ah kala duwanaansho iyo isku hallayntooda. Maadaama tignoolajiyadu ay sii socoto, muhiimadda isku xidhayaasha tayada sare leh sida isku xidhka dheddigga ee FDFD ee si buuxda u dahaaran lama sheegi karo si loo hubiyo in nidaamyada korontada ay si hufan oo ammaan ah u shaqeeyaan.
