Chii PVC, uye chii chiri kukanganisa wayo muviri womunhu

Chii PVC? Ichi acho ndiwo polyvinyl chloride. Nderake boka thermoplastics - mapurasitiki, izvo pashure chigadzirwa achiumba muitiro anoramba ane mano kuoresa. PVC mambure acho rinoumbwa 43 muzana ethylene. The yasara 57 muzana - unobatanidzwa kuiisa chlorine.

PVC zvinhu - chii? Polyvinyl chloride ukasunungurwa muchimiro upfu uye rinoshandiswa sectors vazhinji upfumi. The yakakurumbira chigadzirwa, iro rinoshandiswa pagadzirwe ichi zvinhu - zviri mahwindo epurasitiki. Nokuti kugadzirwa hwindo Dzimwe particulate polyvinyl chloride iri akawedzera chaiwo pigments, stabilizers, modifiers nezvimwe yokuvirisa zhinji. Pamusana kwavari, chigadzirwa rinova husingakuvadzi invulnerable zvakananga chezuva, tembiricha nezvimwe zvezvakatipoteredza zvinhu nokufamba kwezvakatipoteredza.

Chii PVC? mumuviri zvinhu

The chikuru chinoratidza PVC zvinhu - nayo simba. Maererano ehupfumi ayo PVC ari kushanda kwete pasi deformation nezvimwe zvemaziso kunetseka. The chaizvo chete mwero simba iri zvinhu kunoenderana nemamiriro macromolecules uyewo nemamiriro polymer.

PVC zvinhu - chii? mamiriro

Izvi zvinhu kunoratidzwa sechinhu incombustible thermoplastic zvinhu izvo anongokurukurwa kuti machine psac pamusoro kwakajairika muchina maturusi uye hunogona kungoparara welded zvinopisa mhepo ari kudziya 200-300 Celsius. Uyezve, unogona kuomerera dzakasiyana-siyana adhesives (zvinowanzoreva perchlorvinyl yakavakirwa nebwe). Uyezve, zvinoshingaira zvinhu anogona vakanamatira huni, kongiri uye simbi zvigadzirwa. PVC haatyi dzokuteerera nemarudzi mazhinji acids uyewo aliphatic, uye chlorinated zvinonhuwirira Mahydrocarbon. isimba namira uye welds vanenge 85-90 muzana simba acho.

Nokuda simba raro pakakwirira uye vachikotama elasticity polyvinyl kudiwa kukuru pakati vehove vakanga artisanal kubereka okumusoro zvikamu Kukosa, uyewo tsvimbo yechando hove. Practice inoratidza kuti zvinhu izvi usaora ehupfumi dzavo zvichishanyira kutonhora zviri kubvisa madhigirii 45 Celsius.

dielectric ehupfumi

Kutaura nezvemabasa PVC ehupfumi vari zvakakodzerawo kucherechedza kuti PVC ari insulator akanaka (kwete zvidzidzo Magetsi kuburikidza pacharo). Zvisinei, kana neshungu kuti tembiricha 85 Celsius kana kupfuura rinoita zvinhu nokukurumidza anorasikirwa ehupfumi izvi. Kana uremu, kuti arambe achirema pamusoro PVC kunorema kupfuura polyethylene, asi vakareruka kupfuura PTFE uye phenol formaldehyde epurasitiki.

High PVC moto nemishonga kunokwanisika nokushandisa ayo gadzira chimwe chezvinonhuwira akadai kuiisa chlorine. Ndizvo kunoderedza ngozi flammability zvakaoma PVC.

mushonga ehupfumi

Sezvatamboona, kuti PVC ndiye anoita kuti hatiwani migumisiro dzimwe mhando acids. Ichokwadi - PVC haachinji ehupfumi ayo pasi zvinoitwa alkalis, peturu, neparafini, munyu zvinogadzirisa, uye simbi. Uyewo, kusvikira 60 Celsius rinoita zvinhu zviri husingakwanisi hydrochloric uye formic acid. PVC ndiye husingakwanisi oxidation uye kugara glycerol, kwemafuta uye glycols. Kana doro, ari polyvinyl chloride hakusi soluble mu ethyl uye methyl doro, yepamusoro doro, uyewo lubricants uye mafuta. Ko nyore zvinokonzerwa kwayo uye acidic tsvina mvura.

Aripiko richishandiswa?

Chii PVC, hatina kare akawanikwa kunze, zvino ngatimbotaura pamusoro sectors ichi zvinhu rinoshandiswa. Polyvinyl chloride zvinowanzodavirwa kushandiswa pakugadzira kusanduka epurasitiki machira (nokuti pamadziro uye flooring zvokuvakisa), mafirimu, vanodzivirira magiravhusi uye nezvimwe zvakawanda uye zvigadzirwa. Vanachandagwinyira non-plasticized mapaipi PVC dzinoitwa invulnerable kune migumisiro ngura, uyewo dzimwe madhoo uye mahwindo. The zvemagetsi munda zvinhu rakashandiswa mudziye waya. Ita naye zvakanaka matoyi, Stationery uye zvemitambo nhumbi. PVC faibha inoshandiswa kugadzira utava hove, zvokurapa wakaisvonaka, knitwear uye siyana Sefa micheka mumaindasitiri. Sezvaunogona kuona, PVC rinoshandiswa zvinenge zvose maindasitiri neimba.

Zvinoitwa PVC zvigadzirwa

In musika wokuRussia vanogona kuwana zvigadzirwa zvakadaro dzakawanda PVC:

1. The flooring (nemamwe mazwi - linoleum).
2. Film.
3. PVC aenzana.

Pasi apa, isu muchidimbu kutarisa nerimwe pakubhadhara izvi mishonga pamusoro apa.

Chii PVC-zvemapuranga? Ichi pemvura umo chaiyo PVC usina kukonekita, akaronga kuti kuisa pasi yaishandiswa. Pangave somunhu nyore sikweya, uye magadzirirwo kunzwisisa chimiro.

PVC firimu - chii? Maererano ehupfumi ayo, ndiko zvikuru yakajeka, kuchinja uye zvishoma stretchy zvinhu. Sedzimwe zvigadzirwa zviri husingakwanisi alcohols uye acids, asi ane basa rakasiyana nemamwe mano kupfuura oxygen. Ndokusaka mumidziyo, rakazara muna firimu ichi kwenguva refu nguva havazotadzi Svoge mharidzo.

Chii PVC ukomba? zvinhu izvi, iro rakashandiswa vasapedze pamusoro ceilings uye masvingo ari dzakasiyana mudzimba. Anowanzoshandisirwa cladding masvingo mukicheni uye muimba yokugezera.

Sezvo polyvinyl chloride kunokanganisa muviri womunhu?

Vinyl chloride pacharwo kunoratidzwa kuva simba chaizvo uturu In combustion inongorira zvine chepfu. In murume, fuma iyi terato-, carcinogenic uye mutagenic kushanda. Somugumisiro, vakawanda zvidzidzo masayendisiti kwakaratidza kuti matambudziko PVC kwevanhu chikonzero nokuora siyana nhengo uye munyama (kusanganisira uropi, mapapu uye chiropa), uye anotyora nhengo dzinobudisa uye hematopoietic gadziriro. With anoramba chiito mukuru kuwanda raive nebutiro chloride Zvingatovaita kuoma tsinga kusvikira kwakakwana kumira kufema. Zvisinei, vagadziri uno kufungwa dzose zvivako izvi, uye saka zvibereko PVC kunyatsonzwisisa rwokugadzira. Modern zvibereko polyvinyl chloride (kana Qualitative) haana kudaro zvinotyisa kukanganisa kwevanhu. Naizvozvo, kuti arege kuzviisa pangozi utano hwavo kana kutenga PVC zvigadzirwa zvinofanira chete kuvimba nyika yakakurumbira vagadziri.

Saka, takaona kuti PVC ndiye uye chii chaizvoizvo rine pamusoro womunhu.
