PVC mu nsinga n'insinga: Imiterere y'ibikoresho by'ingenzi

1. PVC Resin

Resin ya PVC ni polymeri ikoze muri thermoplastic igizwe na polymeri ya monomeri za vinyl chloride. Imiterere yayo ya molekile irangwa na:

(1) Nk'umuti wa thermoplastic, igaragaza plasticity nziza n'ubworoherane.

(2) Kuba hariho imigozi ya C-Cl ikora neza bituma resin igira polarity ikomeye, bigatuma habaho dielectric constant (ε) na dissipation factor (tanδ) byinshi, mu gihe bitanga imbaraga nyinshi za dielectric ku murongo muto. Iyi migozi ikora neza kandi igira uruhare mu gutuma habaho imbaraga zikomeye hagati ya molekile n'imbaraga nyinshi za mekanike.

(3) Atome za chlorine ziri mu miterere ya molekile zitanga ubushobozi bwo kwirinda umuriro hamwe no kurwanya imiti n'ikirere neza. Ariko, izi atome za chlorine zibangamira imiterere ya kristali, bigatuma ubushyuhe budakomera kandi ubukonje budakomera, ibyo bikaba byanozwa binyuze mu kongeramo ibintu bikwiye.

2. Ubwoko bwa PVC Resin

Uburyo bwo gupima PVC burimo: gupima imiterere y’amazi, gupima imiterere y’amazi mu buryo bwa emulsion, gupima imiterere y’amazi mu buryo bwa bulk, no gupima imiterere y’amazi mu buryo bwa solution.

Uburyo bwo gupima polimeri bukoreshwa muri PVC muri iki gihe ni bwo bwiganje mu gukora resin, kandi ubu ni bwo bwoko bukoreshwa mu gukoresha insinga n'insinga.

Resins za PVC zikozwe muri polimeri zigabanyijemo imiterere ibiri:
Resin yo mu bwoko bwa XS: Irangwa n'imiterere y'imyenge, ifata pulasitiki nyinshi, ikora plastike byoroshye, igenzura ryoroshye ryo kuyitunganya, hamwe n'uduce duke twa gel, bigatuma iba amahitamo meza yo gukoresha insinga n'insinga.
Resin yo mu bwoko buto (ubwoko bwa XJ): Ikoreshwa cyane cyane mu bindi bicuruzwa bya pulasitiki.

3. Imiterere y'ingenzi ya PVC

(1) Imiterere y'Ubushyuhe bw'Amashanyarazi: Nk'ibikoresho bya dielectric bifite polar nyinshi, resin ya PVC igaragaza imiterere myiza ariko iri hasi gato y'ubushyuhe bw'amashanyarazi ugereranije n'ibikoresho bitari polar nka polyethylene (PE) na polypropylene (PP). Ubushyuhe bw'ingano burenga 10¹⁵ Ω·cm; kuri frequency ya 25°C na 50Hz, dielectric constant (ε) iri hagati ya 3.4 na 3.6, ihinduka cyane bitewe n'impinduka z'ubushyuhe n'impinduka; factor yo gukwirakwiza (tanδ) iri hagati ya 0.006 na 0.2. Ingufu zo kwangirika ziguma hejuru mu bushyuhe bw'icyumba n'impinduka z'ingufu, ntizibangamirwa na polarity. Ariko, kubera igihombo cyayo kinini cya dielectric, PVC ntikwiriye gukoreshwa mu gukoresha voltage nyinshi n'impinduka nyinshi, ikunze gukoreshwa nk'ibikoresho byo gukingira insinga za voltage nke n'iziciriritse ziri munsi ya 15kV.

(2) Gukomera mu gusaza: Nubwo imiterere ya molekile igaragaza ko ihindagurika ryiza mu gusaza bitewe n’imigozi ya klorini na karuboni, PVC ikunda kurekura kloride ya hydrogen mu gihe cyo kuyitunganya munsi y’ubushyuhe n’imbaraga za mekanike. Oxidation itera kwangirika cyangwa guhuza, bigatera ibara rihinduka, gucika intege, kugabanuka gukomeye mu miterere ya mekanike, no kwangirika k’imikorere y’amashanyarazi. Kubwibyo, hagomba kongerwamo ibintu bikwiye bihamye kugira ngo hongerwe ubushobozi bwo kudasaza.

(3) Imiterere ya Thermomechanical: Nk'umubumbe udafite ishusho, PVC iboneka mu miterere itatu y'umubiri ku bushyuhe butandukanye: imiterere y'ikirahure, imiterere yo hejuru, n'imiterere y'umuvuduko utose. Iyo ubushyuhe bw'ikirahure (Tg) buri hafi ya 80°C n'ubushyuhe bw'umuvuduko buri hafi ya 160°C, PVC mu miterere yayo y'ikirahure ku bushyuhe bw'icyumba ntishobora kuzuza ibisabwa mu gukoresha insinga n'insinga. Guhindura ni ngombwa kugira ngo ubushyuhe bw'icyumba burusheho gukomera mu gihe hagumana ubushyuhe buhagije n'ubukonje burambye. Kongeramo pulasitiki bishobora guhindura neza ubushyuhe bw'ikirahure.

IbyerekeyeONE WORLD (OW Cable)

Nk’umucuruzi ukomeye w’insinga n’insinga, ONE WORLD (OW Cable) itanga ibikoresho bya PVC byiza cyane byo gushyiramo insinga no kuziba, bikoreshwa cyane mu nsinga z’amashanyarazi, insinga z’ubwubatsi, insinga z’itumanaho, n’insinga z’imodoka. Ibikoresho byacu bya PVC bifite insinga z’amashanyarazi nziza, zirinda umuriro, kandi zirwanya ikirere, byubahiriza amahame mpuzamahanga nka UL, RoHS, na ISO 9001. Twiyemeje gutanga ibisubizo bya PVC byizewe kandi bihendutse bijyanye n’ibyo abakiriya bacu bakeneye.
