Shure firimu nokuti kavha: tsananguro uye mhando

With kukura mumunda kwemakemikari ruzivo uye kuvandudza zvinhu zvayo. Wandei indasitiri chidimbu vari kavha zvinhu, izvo Manufacturers nonfood nezvokudya vaine zvivako zvavo uye unongotaura. kukurumbira Great akapiwa vanodzokera firimu kuti kavha, pikicha iyo chinopiwa pazasi.

Zvinoumba unyana firimu

The musiyano chikuru vanodzokera firimu kukwanisa rayo ndizvipete kuti saizi chaienzanirana chipfuro chinhu. compression Its kunoitika pasi kumusoro tembiricha. Mushure kutonhora, mashoko anotora chimiro mumapepa chigadzirwa. Saka vanodzokera firimu nokuda kavha anogona kuponesa hwokugadzira uye mumuviri unhu zvigadzirwa siyana, kusanganisira kuvakwa uye zvokudya.

Zvichienderana yezvinoreva kushandiswa vanogadzira kupa zvimwe ari firimu. Somuenzaniso, mashoko apertured firimu rinobudiswa kuti bhekari zvigadzirwa. The hwaro chete mbishi zvinhu anoita PVC kana polyolefin pellets. Kana PVC ari dzinozivikanwa mu kudiwa nokuda kwayo mukurumari, kuti POF kunobatsira pakuti haana netsvina hunokuvadza. Kazhinji, kuti vanodzokera firimu kuti hombodo kavha kana chikafu midziyo rinobudiswa kubva polyolefin zvokunyama.

Application firimu

Zvichienderana vanodzokera firimu indices uye thicknesses angashandiswa zvinangwa zvakasiyana. Saka, kana chiri chiduku mwero clamping, mashoko anogona kushandiswa nyoro zvinyama zvigadzirwa, zvigadzirwa yakadhindwa kana nezvokudya. Kusiyana neizvi, vanachandagwinyira shrinkage anobvumira kubata rinorema zvokuvakisa, uyewo zvinhu nevasiri mureza siyana. Kwakadaro anorondedzera vanodzokera firimu nokuda kavha nematanda inotaura boka pati, zvakanaka kugadzirira navo dzaifanoiswa. Panzira, nokuti kugadzirwa yakadaro polyvinyl chloride firimu rikashandiswa. Zvakakosha kuziva kuti kuwedzera wokudzivirira uye zvekupfakira kushanda firimu inogona kushandiswa nokuda kuona pamasikiro chigadzirwa. The vanodzokera kavha rinowanzoshandiswa akaputirwa Wallpaper, matoyi, magazini, achipa chigadzirwa dzimwe kubwinya uye chivheneke.

zvinhu unhu

Firimu inowanika zvakasiyana zvinogona, izvo zvinosiyana zvichienderana kavha muchina. Achitaura kusarudza yakananga chigadzirwa, unofanira kuteerera maitiro maviri - ari chikamu shrinkage uye ukobvu. Kazhinji, asi chikamu shrinkage ari longitudinal mudzinza sezvakarayirwa 60-70%, uye muchinjikwa chikamu - kubva 10 kusvika 50%. On simba kavha unochinja pakukora. The thinnest firimu kuti ndizvipete kavha, akaita maererano nemitemo zvokugadzira zvinhu mutoo, ane Ukobvu 10 microns. High zvakasiyana zvinogona kusvika 200 microns. Uyezve, zvinokosha kuti kufungawo tembiricha mamiriro panguva iyo mashoko inogona kushandiswa. Paavhareji zvinobvumidzwa tembiricha mukoridho kubva -40 kusvika +50 ° C, kunyange zvichienderana chikumbiro unyanzvi anogona kuwedzera yokuvirisa kuti tiwedzere Range ichi.

uchishandisa ehupfumi

Pane chinhu chinokosha akagadzirwa unhu akadzadzwa anenge ose okunatsiridza chidya mafirimu. Pakutanga chakakwirira zvokuimba simba kuti kutanga unodzivirira kavha unhu. Uyewo, kwakadai zvinhu kunoratidzwa mubatanidzwa mukana wokushandiswa uye pachena. Kupikiswa paumbwe mvura yaiitwa yakapfupikiswa uye mwando nemishonga uyewo kuwedzera zvingangoitika kushandiswa firimu.

Chokwadi, anenge akasiyana pfuma, iyo ine vanodzokera firimu nokuda kavha, ndiye anokwanisa kushandura Linear parameters uye tora Maumbirwe chipfuro chigadzirwa. Chimwe chinhu ndechokuti zvinoda anokosha midziyo, zvokurimisa ari wrapping. Asi munguva yemberi gobvu uye chiine zvakakodzera ndichapa zviviri zvinokosha zvaizomunakira. Chokutanga, zvicharangarirwa pamwe kudzivirira richizarurwa uye chepiri ari muitiro kutakura nhumbi bato achatora kushoma nzvimbo. Kana isu kutaura nomumwe ehupfumi, pakati pavo vari munharaunda kuchengeteka uye chitarisiko. Unhu aya rinokosha dikidiki firimu chigadzirwa.

mhando

Kunyange zvazvo vakawanda firimu zvinhu zvingangoita nokupisa-yokuvira kutarisa chete, vane misiyano yakawanda. Technologists dzinoiswa kavha kubudikidza mhando mamiriro, zvakaoma, kuvapo zvimwe modifiers zviri murwiyo, saizi, chimiro, uye saka nyaya. D. Mumwe zvinokosha zviri kuparadzana ndiyo mhando mamiriro. Zvikuru yakakodzera kushandisa runoonekwa kuti muchinjikwa firimu twi jira. Hazvina kuisa chinyorwa tichitarisa simba, asi mamiriro ayo vakachengeta Zvakanyanya Kunaka Panguva Yepamuviri pakuenzanisa rejira ukobvu uye simba tensile. pfuma iyi inokosha kana Somuenzaniso, rinoshandiswa kuti ndizvipete firimu kavha kuti lining mu bhuku guru. Usati kushumira vashandi vari iyi, basa kuchengetedza kufadza zvinowanikwa nzvimbo uye panguva iyoyowo kuona kuvimbika firimu pachayo. Pamusoro kusiyana murwiyo, ipapo yoga zvinhu, izvo ane hydrochloride kuti rabha, polystyrene, polyamide uye kufanana. D. Special nzeve anopiwa kupatsanura maererano nokuwanda firimu akaturikidzana.

The multilayer uye monolayer firimu

Chokutanga, zvinofanira kucherechedzwa kuti dzinokosha kusiyana takatsunga ne mukugadzira nzira. Single-rukoko jira rinobudiswa nezvakaitika extrusion nzira, i.e. kumanikidza epurasitiki guru. Saka zvazvakanakira vakawana zvigadzirwa ingasanganisira wakawedzera viscosity, elasticity, uye pachena. Asi kana ukasarudza ndizvipete firimu nokuda kurongedza zvidhinha kana zvimwe zvokuvakisa, zvakanaka kureva multi-rukoko dzomuzana. zvokunyama kwakadaro zvinoberekwa coextrusion unyanzvi. The musiyano chikuru kugadzira kwacho ndechokuti chaizvo musoro runobereka extruders kushandiswa. Multi-Dzinogara dandemutande unotora paumbwe copolymer uye kunatsiridza asidhi uye copolymer pakati ethylene. firimu mamiriro anogona vanoumba yokuwedzera akaturikidzana akawanda.

chiputiriso configuration

dzakasiyana siyana pamusoro chigadzirwa kavha vanodzokera firimu, pakusarudza zvakatemwa kubudikidza zvechadenga zvigadzirwa. Zvikurukuru, rinoshandisa ukapisa murwi kavha rimwe, boka uye. Kusarudza kutanga chinoshandiswa kushanda chigamba nenhumbi - vanonzi nomumwe kavha. Group nzira rinoshandisirwa munhu chete michina zvigadzirwa wandei pamwe chete ndeiya yakaita unhu. Somuenzaniso, yakadai configuration rinobvumira vanodzokera firimu nokuda kavha pamusoro pallets kuti kwerubwinyo rwakagara rwuripo ukapisa murwi iri rinokosha substrate. Kuwedzera nekuchengeta kavha nzira yakadaro inoita zvinyoronyoro uye njodzi kutakura nhumbi. Ukapisa murwi configuration zvakare anopa kushandiswa nhovo, asi paine kuomarara. Ipfungwa Izvi zvakakodzera kushandisa zvakawanda zvigadzirwa kubva magaba uye mabhuku zvidhinha uye nemabhegi. Mushure kuisira nhumbi nokufukidzwa firimu pakavha.

Release chimiro uye chokuguma

Preparation firimu iri muchikuvadza unokosha ruoko uye anouya muchimiro mabhanzi. Above nomumwe ichitenderera riri nokufukidzwa rwokudzivirira mumuhara yakagadzirwa bepa kana zvakafanana polyethylene. Kazhinji, kuti vanodzokera firimu wrapper rwakapetwa ane makubhiti 500 mm uye anoyera makirogiramu 35. Zvisinei, muna bhizimisi uye kugadzira zvakashandiswa, uye nezvimwe zvinogona Somuenzaniso ane makubhiti 1000 mm uye uremu 50 makirogiramu. Mumwe mupumburu zvinenge Kunoonekwa nokuva Chikwata rine mashoko pamusoro mugadziri, chigadzirwa nokurondedzerwa, kusunungurwa musi, etc. Pakusarudza firimu zvigadzirwa vanofanirawo kuwana ruzivo pamusoro miedzo - .. Zivo operative zvatariswa uye zvinogonekwa kuchabatsira kutenga optimally vakakodzera kavha zvinodikanwa chaizvo.

mhedziso

kavha zvinogadzirwa musika zvayakafara kwazvo, riri kukonzerwa guru kudiwa zvibereko boka iri. Quality kavha kunodiwa nhasi muminda siyana: nezvokudya kubudiswa kune nehoro. Sezvo tsika chinoratidza kushandiswa kupisa-vanodzokera zvinhu, vanenge 90% okuwana ichi rinoshandiswa mukushandira nenhumbi asiri chikafu. Zvisinei, vakawedzera kwezvakatipoteredza kuchengeteka uye mukana kuwedzera kushandiswa kavha kuti miriwo, bhekari zvigadzirwa, Semi-dzapedza zvinhu uye zvichingodaro. D.

Kuvandudzwa vanodzokera firimu nokuda kavha kwenhumbi maererano makachengeteka. Kuomarara, misodzi nemishonga uye tightness - izvi unhu zvikuru muna kwerunyararo zvokuvakisa, iyo -. Wallpaper, nyaya yakakodzera, Tile, Panel lining, etc. Uyewo, pane zvinoitwa kuwedzera kudiwa dzakagadzirirwa mafirimu okunatsiridza zvinopa zvimwe unongotaura ehupfumi.
