Horudhac silig PVC qiiq hooseeya iyo kaabadaha
PVC (Polyvinyl Chloride) qiiq yar iyo xeryahooda fiilada waa qalab heerkulbeeg gaar ah oo loogu talagalay in lagu yareeyo qiiqa iyo qiiqa sunta sii daaya inta lagu jiro gubashada. Tani waxay ka dhigaysaa door lama huraan u ah codsiyada halka badbaadada dabku ay tahay mudnaanta koowaad. Caadi ahaan loo isticmaalo dahaarka iyo jaakadaha fiilooyinka korantada, xeryahooda ayaa bixiya dhowr astaamood oo muhiim ah:
Halabuurka:Xeryahooda PVC ee qiiqa hooseeya waxaa lagu qaabeeyey isku-dar ah xabagta PVC, balaastikada (sida dioctyl phthalate iyo tri-2-ethylhexyl trimellitate), dib-u-celinta ololka (tusaale, antimony trioxide, trihydrate aluminium, iyo zinc borate), xasiliyayaal (calcium/zinc-ku-salaysan), buuxinta (kaalshiyam lubricants).
Guryaha qiiqa hooseeya:Si ka duwan sida caadiga ah ee PVC, kaas oo yareyn kara aragtida ilaa 90% 30 daqiiqo oo keliya sababtoo ah qiiq cufan, xeryahooda PVC ee qiiq yar ayaa loo habeeyay si ay u buuxiyaan heerarka badbaadada sida BS EN 61034. Xeryahaani waxay u oggolaanayaan ugu yaraan 60% gudbinta iftiinka inta lagu jiro gubashada, si weyn u wanaajiya amniga.
Dib u Dhigista Ololka: PVC asal ahaan waxay leedahay sifooyin dib u ololaya sababtoo ah waxa ku jira koloriin, taas oo lagu wanaajiyey waxyaabo dheeri ah oo ololka celinaya. Iskudhisyadani waxay la kulmaan heerar adag sida IEC 60332-1-2, UL VW1, iyo E84
Codsiyada:Caadi ahaan loo isticmaalo bay'ada khatarta sare leh sida xarumaha xogta, tunnelyada, diyaaradaha, gawaarida tareenada, iyo dhismayaasha dadweynaha, siliga PVC ee qiiqa yar iyo xeryahooda fiilooyinka ayaa muhiim u ah yaraynta khatarta la xiriirta qiiqa iyo qiiqa sunta ah haddii uu dab dhaco.
Caqabadaha Habraaca Guud iyo Xalka Sigaarka PVC ee qiiqa Yar iyo Isku-dhafka Cable
Ka-hortagga xeryahooda PVC ee qiiq yar waxay ku lug leedahay maaraynta caqabado kala duwan, gaar ahaan habayntooda adag awgeed. Hoosta, waxaan ka wada hadalnaa qaar ka mid ah arrimaha habaynta ee ugu caansan iyo xalalkooda:
1. Mawduuca Buuxiyaha Sare ee u horseedaya Dhaqdhaqaaq Xumo iyo Torque Sare
Loollan:Si loo gaaro guryaha qiiqa hooseeya, xeryahooda PVC waxay inta badan ka kooban yihiin heerar sare oo ah buuxinyaal aan dabiici ahayn sida aluminium trihydrate (ATH) ama magnesium hydroxide (Mg (OH) ₂) - caadi ahaan 20-60% miisaan ahaan. Halka kuwa buuxinaya ay yareeyaan qiiqa iyo ololka, waxay kordhin karaan viscosity, yarayn karaan socodka, waxayna sababi karaan xirashada qalabka.
Xalka:
Ku dar qalabka wax lagu farsameeyo sida saliidaha gudaha/dibadda (tusaale, kalsiyum stearate, waxes polyetylen, amawax lagu daro silikoon) at 0.5-2.0 phr si loo yareeyo viscosity iyo kor loogu qaado socodka.
Isticmaal saamiga L/D sare ee mataanaha-screw extruders si aad u wanaajiso isku darka iyo kala firdhinta buuxinta.
Shaqaalaysii hababka cajiinka leh quudinta xoogga conical si aad u hubiso isku-darka isku midka ah.
Dooro buuxiyeyaal leh cabbirrada walxaha la kontoroolo iyo daawaynta dusha sare si loo wanaajiyo iswaafajinta loona yareeyo nabarrada.
2. Xasiloonida kulaylka
Loollan:PVC waxay hoos u dhigi kartaa inta lagu guda jiro farsamaynta, gaar ahaan buuxinta sare iyo culeysyada ololka, sii daaya gaaska hydrogen chloride (HCl) taasoo u horseedda xaalufka walxaha, midab-doorsoomidda, iyo daxalka qalabka.
Xalka:
Ku dar qaboojiyaha kulaylka sida kalsiyum/zinc-ku-salaysan xasiliyayaasha 2-4 phr si aad uga takhalusto HCl ugana hortagto xaalufka.
Isticmaal saliid soybean ah oo Epoxidized ah (ESO) sidii isku-dejin si kulaylka iyo xasiloonida sawireed loo hagaajiyo.
Si sax ah u xakamee heerkulka habaynta (160-190°C) si aad isaga ilaaliso kulaylka.
Ku dar antioxidants phenolic (tusaale, Bisphenol A at 0.3-0.5%) si kor loogu qaado caabbinta gabowga inta lagu jiro habaynta.
3. Tahriibka balaastiga
Loollan:Balaastiijiyeyaasha loo isticmaalo in lagu wanaajiyo dabacsanaanta waxay ku haajiraan kulayl sare (tusaale, xarumaha xogta), taasoo horseedaysa dhismo haraaga ah oo faragelin kara gudbinta calaamadaha ama yaraynaysaa cimriga fiilada.
Xalka:
Isticmaal balaastiijiyeyaasha polymeric-ka ah ee aan guurin halkii aad ka isticmaali lahayd kuwa monomeric ah (tusaale, DOP, DINP) si loo yareeyo socdaalka.
Samee qaacidooyinka plenum “aan-dareere ahayn”, sida ay hormoodka u tahay OTECH, si looga hortago guuritaanka balaastiigga ee deegaan heerkulkiisu sarreeyo.
Dooro balaastikada sida TOTM, kuwaas oo leh isbeddel hoose oo ku habboon codsiyada heerkulka sare.
4. Isku-dheellitirka Dib u dhaca Ololka iyo Xakamaynta qiiqa
Loollan:Kordhinta dib u dhaca ololka iyada oo loo marayo waxyaabo lagu daro sida antimony trioxide (3-5%) ama xeryahooda brominated (12-15%) waxay kordhin karaan sii daynta qiiqa, taas oo ka dhigaysa mid adag in la isku dheelitiro labadaba. Sidoo kale, wax-buuxiyeyaasha sida calcium carbonate waxay yareyn karaan qiiqa laakiin waxay hoos u dhigi karaan tusaha oksijiinta, taasoo saameynaysa dib u dhaca ololka.
Xalka:
Isticmaal isku-darka dab-demiska (tusaale, ATH oo leh zinc borate) si aad u wanaajiso dib-u-dhacyada ololka iyo xakamaynta qiiqa labadaba. ATH, tusaale ahaan, waxay sii deysaa uumiga biyaha si ay u carqaladeeyaan gubashada oo ay u sameeyaan lakab ilaalin ah oo dhuxul ah, kaas oo yareeya qiiqa.
Ku xaddid culeyska CaCO₃ ilaa 20-40 phr si aad isu dheelitirto inta u dhaxaysa kharashka, xakamaynta qiiqa, iyo dib u dhaca ololka, maadaama xaddi xad-dhaaf ah ay yarayn karto tusaha ogsijiinta.
Sahami qaababka PVC-ga ee isku-tallaabta ah, sida shucaaca PVC-ku-xiran, si kor loogu qaado daahitaanka ololka iyada oo aan aad ugu tiirsanayn waxyaabaha halogenated.
5. Geedi socodka iyo tayada dusha sare
Loollan:Buuxinta sare iyo maadada wax lagu daro waxay u horseedi kartaa dhamaystirka dusha sare ee liita, dhinta qulqulka, iyo extrusion aan joogto ahayn, kaas oo saameeya muuqaalka iyo waxqabadka sheyga fiilada ugu dambeeya.
Xalka:IsticmaalSILIKE budada silicone LYSI-100A. Taniwax lagu daro silikoon ku salaysanwaxaa si weyn loo isticmaalaa sida awax lagu daro habayn wax ku ool ahNidaamyada xabagta ee PVC-ku habboon si loo hagaajiyo sifooyinka wax-qabadka iyo tayada dusha sare. Sida qulqulka xabagta ee ka wanaagsan, buuxinta caaryada & sii deynta, qulqulka qulqulka yar, iyo isugeynta hoose ee khilaafka, mar weyn, iyo caabbinta naaxinta…
