Njirimara nka na nyocha ngwa nke PVC Tarpaulin Structures

PVC tarpaulin bụ ihe na-arụ ọrụ nke a na-ejikarị na ụlọ nwa oge, ihe mkpuchi ụlọ nkwakọba ihe, mgbasa ozi n'èzí, na ubi ndị ọzọ. Nhazi nhazi ya na-emetụta ịdịte aka nke ngwaahịa ahụ, mgbochi mmiri, yana ngbanwe gburugburu ebe obibi. Edemede a na-akọwa n'ụzọ doro anya njirimara nhazi na uru teknụzụ nke PVC tarpaulin site n'echiche nke ihe mejupụtara ihe, nhazi interlayer, njirimara arụ ọrụ, yana ihe ngosi ngwa ngwa.

 

1. Ihe mejupụtara ihe bụ isi nke PVC Tarpaulin

Ihe bụ isi ihe dị na PVC (polyvinyl chloride) tarpaulin bụ polyvinyl chloride resin, nke a na-eme ka ọ bụrụ ihe mejupụtara polymer site na ịgbakwunye ihe mgbakwunye dị ka plasticizers, stabilizers, na UV stabilizers. Plasticizers (dị ka phthalates) na-akwalite mgbanwe nke ihe, na-enye ya ohere ịnọgide na-enwe ductility ọbụna na obere okpomọkụ. Ihe nkwụsi ike dị ka calcium zinc ma ọ bụ organotin na-akwalite nguzogide okpomọkụ na nguzogide ịka nká, na-agbatị ndụ ọrụ tarpaulin. Ụfọdụ ngwaahịa ikpeazụ- na-etinyekwa ihe ndị na-ere ọkụ ma ọ bụ ihe mgbochi iji mezuo ihe ngwa chọrọ.

 

II. Ọtụtụ-ụkpụrụ ụkpụrụ nhazi ihe mejupụtara

PVC tarpaulins ọgbara ọhụrụ na-eji ọtụtụ-Layer co- extrusion ma ọ bụ mkpuchi ihe mejupụtara iji mepụta ọkwa ọrụ dị iche iche:

Oyi akwa (akwa nkwado): Ejiri eriri polyester siri ike (dị ka PET) ma ọ bụ eriri enyo mee, ọ na-enye ike nkwụsi ike nke tarpaulin na nkwụsi ike akụkụ, na-egbochi nrụrụ nke ike mpụga kpatara.

oyi akwa na-arụ ọrụ nke etiti: Ihe mejupụtara ihe nkiri PVC bụ isi, a na-ejikọta ya na oyi akwa site na ikpo ọkụ- ịgbaze ma ọ bụ kalenda. Igwe oyi akwa a na-ekpebi arụmọrụ tarpaulin. Dịka ọmụmaatụ, ịhazigharị njupụta PVC nwere ike nweta ọkwa enweghị mmiri (dịka ọmụmaatụ, iru IPX7), ebe ị na-agbakwunye obere carbon ojii na-eme ka nguzogide UV dịkwuo elu (ụkpụrụ UF karịrị 50+).

Ngwunye ọgwụgwọ elu: A na-eji polyurethane (PU) ma ọ bụ acrylic varnish kpuchie ụfọdụ ngwaahịa iji mepụta ihe nkiri nchebe na-eyi-na-eguzogide na ntụpọ{1}, ma na-emekwa ka ọ dị nro n'elu iji belata uzuzu na mkpokọ mmiri ozuzo.

 

III. Mmejuputa ihe owuwu nke njirimara arụrụ arụ

Nhazi nhazi nke PVC tarpaulins na-emetụta arụmọrụ ha n'ezie:

Mkpuchi mmiri: Ihe mkpuchi PVC na-aga n'ihu, nke siri ike (na-adịkarị 0.1-0.5mm) na-enye mgbochi mmiri zuru oke. A na-eji nnukwu ịgbado ọkụ{3} ma ọ bụ teepu akara agbado akwa iji hụ na ọ na-agbapụta{4}} ọbụna n'okpuru ikpughe ogologo oge na mmiri ozuzo na snow.

Mgbochi ihu igwe: Otu nkesa nke ndị na-anabata UV n'elu, jikọtara ya na mmetụta synergistic nke oyi akwa mgbochi ịka nká, na-eme ka arụmọrụ kwụsiri ike na okpomọkụ sitere na -30 ogo ruo ogo 70, yana ndụ ọrụ mpụga nke afọ 5-10.

Mechanical Ike: Warp na weft ike tensile n'ozuzu karịrị 200N/5cm (dị ka DIN ụkpụrụ), na ike ndọkasị karịa 150N, na-eme ka ọ na-eguzogide ọgwụ ibu ike dị ka ike ifufe na snow nchịkọta.

 

IV. Ihe ngosi Ngwa a na-ahụkarị yana ndakọrịta n'ụdị

Ọnọdụ ngwa dị iche iche na-etinye ihe dị iche iche chọrọ na ihe owuwu PVC tarpaulin:

Ihe owuwu nwa oge (dị ka ụlọ ntu enyemaka ọdachi): Na-emesi ike dị fechaa na nrụzi ngwa ngwa, ha na-eji okpukpu abụọ{0}} oyi akwa, ihe nrụnye ikuku nwere frim alloy aluminom yana akwa ime maka mkpuchi ọkụ.

Ihe mkpuchi ụlọ nkwakọba ihe: Na-emesi ike ibu{0}} ibu na nkwụsi ike, agbanyere ihe mkpuchi nchara nchara nchara ma ọ bụ eriri Kevlar iji gbochie nsị site na ihe dị nkọ.

Ngosipụta mgbasa ozi: N'ịgbalị maka nnyefe ọkụ dị elu na saturation agba, akwa akwa obibi akwụkwọ na-ejikọta ya na mkpụrụ PVC site na teknụzụ ọgwụgwọ UV iji hụ na eserese na-adịgide adịgide na doro anya.

Ihe ohuru ohuru na PVC tarpaulin na-aga n'ihu na-ebugharị ngwa ya na mpaghara ndị ọzọ. N'ọdịnihu, na iwebata mgbakwunye enyi na enyi gburugburu ebe obibi (dị ka bio{1}) plasticizers dabeere) na smart ihe (dị ka okpomọkụ{2}}nwere mmetụta{3} mkpuchi mkpuchi), PVC tarpaulin na-atụ anya na ọ ga-enweta n'ihu ọganihu na arụmọrụ na nkwado, na-enye ndị ọzọ nke ọma ngwọta maka ọgbara ọhụrụ injinia na ọha mkpa.
