Isingeniso Sentambo Ephansi Yentuthu Yentuthu kanye Nezinhlanganisela Zekhebula
I-PVC (i-Polyvinyl Chloride) yentuthu ephansi (i-Polyvinyl Chloride) yezintambo nezinhlanganisela zekhebula ziyizinto ezikhethekile ze-thermoplastic eziklanyelwe ukunciphisa intuthu nokukhishwa kwegesi enobuthi ngesikhathi sokusha. Lokhu kubenza babe ukukhetha okubalulekile kwezicelo lapho ukuphepha emlilweni kubaluleke kakhulu. Ivamise ukusetshenziselwa ukwahlukanisa nokufaka amabhantshi ezintambo zikagesi, lezi zinhlanganisela zinikeza izici ezimbalwa ezibalulekile:
Ukwakhiwa:Izingxube ze-PVC zentuthu ephansi zenziwe ngenhlanganisela ye-PVC resin, plasticizers (njenge-dioctyl phthalate kanye ne-tri-2-ethylhexyl trimellitate), izinto ezibuyisela ilangabi (isb., i-antimony trioxide, i-aluminium trihydrate, ne-zinc borate), iziqinisa (i-calcium/zinc-based), izigcwalisi (calcium carbonate), kanye ne-lubricants.
Izici zentuthu ephansi:Ngokungafani ne-PVC evamile, enganciphisa ukubonakala kufika ku-90% emaminithini angu-30 nje ngenxa yentuthu eminyene, izinhlanganisela ze-PVC zentuthu ephansi zenziwa ukuze zihlangabezane nezindinganiso zokuphepha ezifana ne-BS EN 61034. Lezi zinhlanganisela zivumela okungenani u-60% wokudlulisa ukukhanya ngesikhathi sokusha, ukuthuthukisa kakhulu ukuphepha.
I-Flame Retadancy: I-PVC ngokwemvelo inezinto ezivimbela amalangabi ngenxa yokuqukethwe kwayo kwe-chlorine, ethuthukiswa ngezithasiselo ezengeziwe ezivimbela ilangabi. Lezi zinhlanganisela zihlangabezana nezindinganiso eziqinile ezifana ne-IEC 60332-1-2, UL VW1, ne-E84 (inkomba yokusabalala kwelangabi <25, inkomba yokuthuthukiswa kwentuthu <50).
Izicelo:Okuvame ukusetshenziswa ezindaweni ezinengcuphe ephezulu njengezikhungo zedatha, amathaneli, izindiza, amakalishi kaloliwe, nezakhiwo zomphakathi, intambo ye-PVC yentuthu ephansi kanye nenhlanganisela yekhebula kubalulekile ukuze kuncishiswe ubungozi obuhambisana nentuthu nentuthu enobuthi uma kusha.
Izinselelo Ezivamile Zokucubungula Nezixazululo Zezintambo Eziphansi Zentuthu Ye-PVC kanye Nezinhlanganisela Zekhebula
Ukucubungula izinhlanganisela ze-PVC zentuthu ephansi kuhilela ukuphatha izinselele eziningi, ikakhulukazi ngenxa yokwakheka kwazo okuyinkimbinkimbi. Ngezansi, sixoxa ngezinye zezinkinga ezivame kakhulu zokucubungula nezisombululo zazo:
1. Okuqukethwe Kokugcwalisa Okuphezulu Okuholela Ekuhambeni Okubi kanye neTorque Ephezulu
Inselelo:Ukuze kuzuzwe izakhiwo zentuthu ephansi, izinhlanganisela ze-PVC zivame ukuqukatha amazinga aphezulu wezigcwalisi ezingaphili njenge-aluminium trihydrate (ATH) noma i-magnesium hydroxide (Mg(OH)₂) - ngokuvamile engu-20-60% ngesisindo. Ngenkathi lezi zigcwalisi zinciphisa intuthu nelangabi, zingakhuphula i-viscosity, zinciphise ukugeleza, futhi zibangele ukuguga kwemishini.
Izixazululo:
Faka izinsiza zokucubungula njengezithambisi zangaphakathi/zangaphandle (isb., i-calcium stearate, i-polyethylene wax, nomaizithasiselo ze-silicone) ku-0.5-2.0 phr ukuze unciphise i-viscosity futhi uthuthukise ukugeleza.
Sebenzisa ama-extruder we-twin-screw anesilinganiso esiphezulu se-L/D ukuze uthuthukise ukuxuba nokuhlakazeka kwesigcwalisi.
Sebenzisa amasistimu e-kneader ane-conical force feed ukuze uqinisekise ukuhlanganisa okufanayo.
Khetha izihlungi ezinosayizi wezinhlayiyana ezilawulwayo kanye nokwelashwa kwendawo ukuze uthuthukise ukuhambisana nokunciphisa ukuhuzuka.
2. Ukuzinza Okushisayo
Inselelo:I-PVC ingehlisa izinga ngesikhathi sokucutshungulwa, ikakhulukazi ngemithwalo ephezulu yokugcwalisa kanye ne-flame-retardant, ikhiphe igesi ye-hydrogen chloride (HCl) eholela ekulimaleni kwezinto ezibonakalayo, ukushintsha kombala, kanye nokugqwala kwemishini.
Izixazululo:
Engeza izinzisi zokushisa njengezinzinzisi ezisekelwe ku-calcium/zinc ku-2-4 phr ukuze unciphise i-HCl futhi uvimbele ukuwohloka.
Sebenzisa uwoyela wesoya epoxidized (ESO) njengesibambisene sokuqinisa ukufudumala nokusimama kwesithombe.
Lawula amazinga okushisa okucubungula ngokunembile (160-190°C) ukuze ugweme ukushisa ngokweqile.
Faka ama-phenolic Antioxidants (isb, i-Bisphenol A ku-0.3-0.5%) ukuthuthukisa ukumelana nokuguga ngesikhathi sokucubungula.
3. Ukufuduka kwe-Plasticizer
Inselelo:Amapulasitiki asetshenziselwa ukuthuthukisa ukuguquguquka angafuduka ngaphansi kokushisa okuphezulu (isb, ezikhungweni zedatha), okuholela ekwakhiweni kwezinsalela ezingase ziphazamise ukudluliswa kwesignali noma ukunciphisa ubude bekhebula.
Izixazululo:
Sebenzisa amapulasitiki e-polymeric angafuduki esikhundleni sama-monomeric (isb, i-DOP, i-DINP) ukuze unciphise ukufuduka.
Dala amafomula e-plenum "angenawo uketshezi", njengoba kwaqalwa yi-OTECH, ukuvimbela ukufuduka kwe-plasticizer ezindaweni ezinezinga eliphezulu lokushisa.
Khetha ama-plasticizers afana ne-TOTM, anokushintshashintsha okuphansi futhi afaneleka kakhulu ezinhlelweni zokushisa eziphezulu.
4. Ukulinganisa Ukuncipha Kwelangabi Nokucindezelwa Kwentuthu
Inselelo:Ukwenyusa ukuncipha kwelangabi ngezithasiselo ezifana ne-antimony trioxide (3-5%) noma izinhlanganisela ze-brominated (12-15%) kungakhuphula ukukhishwa kwentuthu, kukwenze kube inselele ukulinganisela kokubili izakhiwo. Ngokufanayo, izigcwalisi ezifana ne-calcium carbonate zinganciphisa intuthu kodwa zingase zehlise inkomba ye-oxygen, kuthinte ukubambezeleka komlilo.
Izixazululo:
Sebenzisa inhlanganisela ye-synergistic ye-flame retardant (isb., i-ATH ene-zinc borate) ukuze uthuthukise kokubili ukubambezeleka komlilo nokucindezelwa kwentuthu. I-ATH, isibonelo, ikhipha umhwamuko wamanzi ukuze iphazamise ukusha futhi yakhe ungqimba lwe-char oluvikelayo, olunciphisa intuthu.
Nciphisa ukulayisha kwe-CaCO₃ ku-20-40 phr ukuze uthole ibhalansi phakathi kwezindleko, ukucindezelwa kwentuthu, nokuvinjelwa komlilo, njengoba amanani eqile anganciphisa inkomba ye-oxygen.
Hlola ukwakheka kwe-PVC okuxhumene kakhulu, okufana ne-PVC exhunywe ngemisebe, ukuze uthuthukise ukubambezeleka komlilo ngaphandle kokuthembela kakhulu ezithasiselweni ezine-halogenated.
5. Ukucutshungulwa kanye Nekhwalithi Yokuphezulu
Inselelo:Ukugcwalisa okuphezulu nokuqukethwe okungeziwe kungaholela ekuqedeni kahle kwendawo, i-die drool, nokukhipha okungahambisani, okuthinta ukubukeka nokusebenza komkhiqizo wokugcina wekhebula.
Izixazululo:SebenzisaI-SILIKE i-silicone Powder LYSI-100A. Lokhuisithako esisekelwe ku-siliconeisetshenziswa kabanzi njenge-isithasiselo esisebenzayo sokucubungula i-lubricantamasistimu e-resin ahambisana ne-PVC ukuthuthukisa izakhiwo zokucubungula kanye nekhwalithi ephezulu. Okufana nokugeleza okungcono kwe-resin, ukugcwaliswa kwesikhunta nokukhululwa, i-torque encane ye-extruder, kanye ne-coefficient ephansi yokungqubuzana, i-mar enkulu, nokumelana nokuhuzuka...
1) Intambo ye-PVC yentuthu ephansi nezinhlanganisela zekhebula: i-extrusion ezinzile, ingcindezi encane yokufa, indawo ebushelelezi yocingo nekhebula.
2) Intambo ephansi ye-PVC nentambo: I-Coefficient ephansi ye-Friction, umuzwa obushelelezi ohlala isikhathi eside.
3) Umkhiqizo we-PVC ongazweli: I-Anti-scratch, njengakumashutha e-PVC.
4) Amaphrofayili e-PVC: ukugcwaliswa kwesikhunta okungcono nokukhululwa kwesikhunta, akukho flash isikhunta.
5) Ipayipi le-PVC: isivinini sokukhipha ngokushesha, i-COF encishisiwe, ukushelela kwendawo okuthuthukisiwe, nezindleko ezilondoloziwe.
Uma ubhekene nezinselele ngokucubungula okuhlanganisiwe kwe-PVC kanye nokukhubazeka kwendawo, noma unenkinga yocingo lwe-PVC olunomusi ophansi kanye nokucutshungulwa kwekhebula, zama.I-LYSI-100A Silicone Powder yokukhishwa okushelelayo nokusebenza kahle okuphezulu.
