Zvese Zvaunoda Kuziva Nezve Polyvinyl Chloride (PVC) Plastiki

Polyvinyl Chloride (PVC) ndechimwe chezvinhu zvakasiyana-siyana uye zvinoshandiswa zvakanyanya thermoplastic zvinhu pasi rose. Inozivikanwa nekusimba kwayo, kugona, uye kuramba kune zvakatipoteredza zvinhu, PVC inoshandiswa mumaindasitiri akasiyana siyana, kubva pakuvaka kusvika kune hutano. Muchikamu chino, tichaongorora kuti PVC chii, zvimiro zvayo, mashandisirwo, nezvimwe zvakawanda.

Chii chinonzi Polyvinyl Chloride (PVC)?

Polyvinyl Chloride (PVC) imhando yepolymer yakagadzirwa kubva ku polymerization yevinyl chloride. Yakatanga kugadzirwa muna 1872 ndokutanga kugadzirwa kwekutengesa muma1920s neBF Goodrich Company. PVC inonyanya kushandiswa muindastiri yekuvaka, asi mashandisirwo ayo zvakare ane span signage, hutano hutano, machira, nezvimwe.

PVC inowanikwa mumhando mbiri dzekutanga:

1. Yakasimba PVC (uPVC)-Unplasticized PVC chinhu chakasimba, chinogara chakasimba chinoshandiswa mupombi dzemvura, mahwindo mafuremu, uye zvimwe zvimiro zvekushandisa.
2. Flexible PVC- Yakagadziridzwa nemaplasticizers, inochinjika PVC yakapfava, inopindika, uye inoshandiswa zvakanyanya muzvigadzirwa zvakaita sewaya yemagetsi insulation, pasi, uye inochinjika tubing.

Hunhu hwePolyvinyl Chloride (PVC)

PVC's zvivakwa zvinoita kuti ive chinhu chinofarirwa kune akawanda maapplication:

• Density: PVC yakaoma kupfuura mamwe mapurasitiki akawanda, ane simba rinokwevera rakatenderedza 1.4.
• Durability: PVC inoshingirira kusvibiswa kubva kune zvakatipoteredza zvinhu, makemikari, uye UV mwaranzi, zvichiita kuti ive yakakodzera kune zvinogara kwenguva refu zvigadzirwa.
• Simba: Yakaomarara PVC inozvirumbidza yakanakisa kusimba uye kuoma, nepo inochinjika PVC inochengetedza kuchinjika uye simba.
• Recyclability: PVC inoshandiswa zvakare nyore nyore uye inozivikanwa nekodhi resin "3," iyo inokurudzira kusimba.

Zvinhu zvakakosha zvePVC

• Melting Temperature: 100 ° C kusvika 260 ° C (212 ° F kusvika 500 ° F), zvichienderana nekuwedzera.
• Tensile Simba: Flexible PVC inotangira pa6.9 kusvika ku25 MPa, nepo PVC yakasimba yakatosimba pa34 kusvika 62 MPa.
• Heat Deflection: PVC inogona kumira tembiricha kusvika 92 ° C (198 ° F) isati yakanganisa.
• Corrosion Resistance: PVC inopikisa zvakanyanya kumakemikari uye alkali, zvichiita kuti ive sarudzo yakasimba kune akasiyana maindasitiri.

Mhando dzePVC: Rigid vs. Flexible

PVC inonyanya kuwanikwa mumhando mbiri:

1. PVC yakaoma(uPVC): Fomu iri rakaoma uye rinowanzo shandiswa mukuvaka zvikumbiro semapombi epombi uye siding. Inowanzo kunzi "vin
2. Flexible PVC: Yakazadzikiswa nekuwedzera mapurasitiki, inochinjika PVC inoshandiswa mumashandisirwo apo kukotama kana kuchinjika kunodiwa, senge insulation yetambo dzemagetsi, zvishandiso zvekurapa, uye pasi.

Sei PVC Inoshandiswa Kazhinji?

Kuzivikanwa kwePVC kunobva kune yayomutengo wakaderera, kuwanikwa,uyezvakasiyana-siyana zvezvinhu. Rigid PVC inonyanya kufarirwa kune zvimiro zvekushandisa nekuda kwesimba rayo uye kusimba, nepo inochinjika PVC kupfava uye kuchinjika kunoita kuti ive yakakodzera kune zvigadzirwa zvinoda kukotama, senge yekurapa tubing kana pasi.

PVC inogadzirwa sei?

PVC inowanzogadzirwa kuburikidza neimwe yenzira nhatu dzepolymerization:

• Kumiswa polymerization
• Emulsion polymerization
• Bulk polymerization

Aya maitiro anosanganisira polymerization yevinyl chloride monomers kuita yakasimba polyvinyl chloride, iyo inogona kuzogadziriswa kuita akasiyana ezvigadzirwa.

PVC muPrototype Development: CNC Machining, 3D Printing, uye Injection Molding

Nepo PVC iri chinhu chakakurumbira mumaindasitiri akasiyana, inopa mamwe matambudziko kana zvasvika kune prototyping nekugadzira:

• CNC Machining: PVC inogona kutemwa uchishandisa CNC muchina, asi inopwanya uye inoparadza, saka midziyo yakasarudzika (seyakacheka-simbi inocheka) inodiwa kudzivirira kusakara uye kubvaruka.
• 3D Kudhinda: PVC haiwanzo shandiswa kudhinda kwe3D nekuda kwekuora kwayo. Pamusoro pezvo, inoburitsa magasi ane muchetura kana yapiswa, zvichiita kuti ive chinhu chisina kunyanyonakira chinangwa ichi.
• Jekiseni Molding: PVC inogona kuvajekiseni rakaumbwa, asi kuita uku kunoda kufefeterwa nemhepo kwakaringana uye midziyo isingaore nekuda kwekubuda kwemagasi anokuvadza akaita sehydrogen chloride (HCl).

PVC Inotyisa Here?

PVC inogona kusunungurautsi hunokachidzakana yapiswa kana kupiswa, kunyanya muzvirongwa zvemaindasitiri senge 3D kudhinda, CNC machining, uye jekiseni molding. Izvo zvinhu zvinogona kuburitsa magasi anokuvadza sengechlorobenzeneuyehydrogen chloride, izvo zvinogona kukonzera njodzi dzehutano. Izvo zvakakosha kushandisa kwakaringana kufefetera nemidziyo yekudzivirira panguva yekugadziriswa.

Zvakanakira zvePVC

• Mari-inoshanda: PVC ndeimwe yemapurasitiki anodhura anowanikwa.
• Durability: Inopikisa kukanganisa, makemikari, uye kukanganisa kwezvakatipoteredza.
• Simba: PVC inopa inoshamisa kusimba kwesimba, kunyanya mune yayo yakaoma fomu.
• Versatility: PVC inogona kuumbwa, kuchekwa, uye kuumbwa kuita zvakasiyana-siyana zvezvigadzirwa, zvichiita kuti zvienderane nekushandiswa kwakasiyana-siyana.

Kuipa kwePVC

• Heat Sensitivity: PVC ine hurombo husina kugadzikana hwekupisa, izvo zvinoreva kuti inogona kuchinjika kana kudzikisira pakupisa kwakanyanya kunze kwekunge ma stabilizer awedzerwa panguva yekugadzira.
• Chepfu Emissions: Kana yapiswa kana kunyungudutswa, PVC inoburitsa utsi hunokuvadza, hunoda kunyatsobata uye kuchengetedza mapuroteni.
• Corrosive Nature: PVC inogona kukanganisa kumidziyo yesimbi nemidziyo kana isina kubatwa nemazvo.

Mhedziso

Polyvinyl Chloride (PVC) chinhu chinoshamisa chakasiyana-siyana chinopa yakanakisa chiyero chekugona, simba, uye kuramba kune zvakatipoteredza zvinhu. Mafomu ayo akasiyana, akaomarara uye anochinjika, anobvumira kuti ishandiswe mumaindasitiri mazhinji, kubva pakuvaka kusvika kune hutano. Nekudaro, zvakakosha kuti unzwisise zvingangoitika njodzi dzehutano uye matambudziko mukugadzirisa PVC, kunyanya maererano nekuburitsa kwayo uye hunhu hwekuora. Kana yakabatwa nemazvo, PVC chinhu chakakosha chinoramba chichiita basa rakakosha mukugadzira nekuvaka kwemazuva ano.
