Chii chinonzi PU dehwe? Tinofanira kusiyanisa sei PU dehwe kubva pamatehwe chaiwo?

.PU dehwe chinhu chakagadzirwa nemunhu. Idehwe rekugadzira rinowanzova nechitarisiko uye kunzwa kwedehwe chairo, asi rakachipa, harigari, uye rinogona kunge riine makemikari. .
PU dehwe harisi dehwe chairo. PU dehwe imhando yematehwe ekugadzira. Inogadzirwa nemakemikari fiber zvinhu, nepo dehwe chairo rinogadzirwa uye rinogadziriswa kubva paganda remhuka. Dehwe chairo rinotaurwa pamusika kazhinji ndiro rekutanga rematehwe uye rechipiri rematehwe.
PU dehwe, iro zita rakazara iro rinonzi polyurethane dehwe, chinhu chekugadzira chinogadzirwa nekuisa chekugadzira polymer coating pamusoro pehupfu hwemhuka. Izvi zvipfeko zvinowanzobatanidza polyurethane. PU dehwe rine yakanakisa kupfeka kuramba, kufema, kuramba kuchembera uye kuchinjika. Chimiro chechimiro chakanyanya kufanana nematehwe chaiwo, uye yakatonaka kupfuura ganda rechisikigo mune zvimwe zvinhu zvemuviri. Nekudaro, zvichienzaniswa nematehwe chaiwo, PU dehwe rine mimwe misiyano mukusimba, kuchengetedza uye kuchengetedza kwezvakatipoteredza.
PU dehwe rinogadzirwa sei? Iro zita rakazara rePU dehwe ndeye polyurethane dehwe. Iyo inogadzirwa nekuisa polyurethane resin pajira kana jira risiri rakarukwa, uyezve kuita maitiro akadai sekudziya uye embossing kuti ive nemavara akasiyana, maumbirwo uye ukobvu. PU dehwe rinogona kutevedzera chitarisiko uye kunzwa kweakasiyana matehwe echokwadi, akadai sedehwe remombe, dehwe remakwai, dehwe renguruve, nezvimwe.

Ndezvipi zvakanakira PU dehwe? Kutanga, PU ganda rakareruka uye haringaremedze tsoka. Chechipiri, PU dehwe rinonyanya kupfeka uye harina nyore kukweshwa kana kukuvara. Chechitatu, PU yeganda iri nyore kuchenesa, ingoipukuta nemucheka wakanyorova. Chekupedzisira, PU dehwe rine hushamwari kwezvakatipoteredza uye harizokonzerese kukuvadza kana kutambisa kumhuka.

Saka, ndezvipi zvakaipira zvePU dehwe? Kutanga, PU ganda harifemeki, izvo zvinoita kuti tsoka dzidikitire kana kunhuwa nyore. Chechipiri, PU dehwe harimirire kune tembiricha yakakwira uye rinowanzoita deformation kana kuchembera. Chechitatu, PU ganda harina kupfava uye kugadzikana zvakakwana, uye harina elasticity uye kukwana kwedehwe rechokwadi. Chekupedzisira, PU ganda harina kukwira-kumagumo uye kushatirwa zvakakwana, uye harina kupenya uye kuumbwa kwedehwe chairo.
Nzira dzekusiyanisa PU dehwe kubva pamatehwe chaiwo dzinosanganisira:

Kunobva uye zvinongedzo: Dehwe rechokwadi rinobva paganda remhuka, uye mushure mekutsvuka uye mamwe maitiro, rine yakasarudzika masikirwo uye kubata. PU dehwe iganda rekugadzira, rine polyurethane resin sechinhu chikuru, yakagadzirwa nemakemikari reaction, ine yakanaka kupfeka kuramba, crease kuramba uye kuchembera kuramba.
Chitarisiko uye kubata: Dehwe rechokwadi rinopa yakasikwa uye chaiyo kubata ine yakasarudzika yakasarudzika magadzirirwo. Kunyangwe PU dehwe richigona kutevedzera magadzirirwo uye kubata kwedehwe rechokwadi, rinoratidzika kunge rakagadzirwa zvachose. Ganda rechokwadi rine mitsetse yakajeka, uye chidimbu chimwe nechimwe chakasiyana. Iyo mitsetse yePU yematehwe yakawedzera kusviba uye monotonous. Ganda rechokwadi rinonzwa rakapfava uye rakapfava, rakapfava uye rakatsetseka. PU dehwe rinonzwa kupera simba uye kushoma zvishoma.

Durability: Dehwe rechokwadi rinogara rakasimba, rine kusimba kwakanyanya uye elasticity, uye rinogona kuramba kukanganiswa kwekunze uye kupokana. Kunyangwe PU yeganda ine yakanaka kupfeka kuramba, inogona kusangana nekuchembera, kuputika uye mamwe matambudziko mushure mekushandisa kwenguva refu.
Gadziriro nekuchengetedza: Dehwe rechokwadi rinoda kugadziridzwa uye kutarisirwa nguva dzose, uye vamiririri vematehwe vakasarudzika vanoshandiswa kuchenesa, kunyorova uye kudzivirira mvura. PU dehwe riri nyore kutarisira, ingoripukuta nejira nyoro.
Kudzivirirwa kwezvakatipoteredza: Dehwe rechokwadi rinobva muganda remhuka, uye kune marara mashoma uye kusvibiswa mukugadzirwa kwaro. Sematehwe ekugadzira, PU dehwe rinogona kukonzera kumwe kusvibiswa kwezvakatipoteredza mukugadzira kwayo.
Nezvekunhuwa: Dehwe rechokwadi rine kunhuhwirira kweganda, uye rinowedzera kunhuhwirira nekufamba kwenguva. PU dehwe richava nekunhuhwirira kwepurasitiki kwakasimba. Dehwe rechokwadi richadzikira uye kunhuhwirira sebvudzi rinopisa kana rasangana nemoto. PU dehwe richanyunguduka uye kunhuhwirira sepurasitiki inopisa kana yasangana nemoto.
Kushanda kwezviitiko zvakasiyana

Kupfeka kwezuva nezuva: Zvezvigadzirwa zvematehwe zvekupfekwa kwemazuva ese, senge shangu nemabhegi, vatengi vanogona kusarudza zvinoenderana nezvavanoda uye bhajeti. Kana iwe uchitevera kunyaradzwa uye kufema, ganda rechokwadi isarudzo iri nani; kana iwe ukabhadhara zvakanyanya kumutengo uye kutaridzika kwakasiyana, PU dehwe zvakare isarudzo yakanaka.

Nguva dzakakosha: Mune dzimwe nguva dzakakosha, dzakadai semisangano yebhizimisi, kudya kwemanheru, nezvimwewo, zvigadzirwa zvedehwe zvechokwadi zvinowanzoratidza kunaka uye hunhu hune chiremera. Mune dzimwe nguva dzakajairwa, dzakadai semitambo yekunze, kufamba, nezvimwe, zvigadzirwa zvematehwe zvePU zvinofarirwa nekuda kwekureruka uye kusimba.
Muchidimbu, PU dehwe uye ganda rechokwadi chimwe nechimwe chine hunhu hwavo uye anoshanda mamiriro. Vatengi vanofanira kuita sarudzo zvichienderana nezvavanoda uye bhajeti pavanenge vachitenga.
