Nheyo dzeiyo plastiki molding jekiseni maitiro ekugadzira chikamu chepurasitiki

Zvigadzirwa zvepurasitiki zvakanyoresa budiriro yakasarudzika mumakore makumi mashanu apfuura, iyo inodarika yezvimwe zvinhu zvevatengi.

Parizvino muWestern Europe, huwandu hwekugadzirwa kwe chikweshe zvinhu zvinodarika kugadzirwa kweSimbi.

Kukura kwekushandisa kunonyanya kutsanangurwa nekuwedzera kwezvigadzirwa zvevatengi, zvakanyanya kutsiva mapurasitiki, simbi uye girazi semidziyo yemidziyo, kurongedza, zvekuvaka, zvemagetsi, nezvimwe.

Zvakanakira zvinopihwa nepurasitiki zvinhu zvichienzaniswa nezvimwe zvinhu ndezvizvi:

• Iwo akareruka uye nokudaro anoderedza mari yekufambisa.
• Inogara kwenguva refu uye kazhinji yakasimba uye yakachengeteka.
• Zvinogona kugadzirwa mumakumi ezviuru zvemaumbirwo uye maapplication.
• Ivo vane hunhu hwakanakisa senge thermal, acoustic uye magetsi ekudzivirira.
• Iwe unogona kushandiswa mumashandisirwo ezvokudya.

Mapurasitiki akamisikidzwa zvichibva paDIN 7728 uye DIN 16780 zviyero zvemapurasitiki musanganiswa.

Plastics zvinhu zvakasimukira zvine hunyanzvi zvinodaidzwa kuti mapolymers, anobva kuPetroleum kana Natural Gas, anotakura Carbon C, hydrogen H, oxygen O uye mamwe mamorekuru akadai senitrogen N, chlorine CL, sulfur S kana CO2. Parizvino, 4% chete yemafuta inoshandurwa kuita zvinhu zvepurasitiki.

chikweshe inotorwa kubva mupetroleum nekupisa distillation process (kutsemuka), umo Ethylene, Propylene, Butylene uye mamwe mahydrocarbon anopatsanurwa.

Macromolecules, kana mapurasitiki, anoumbwa nehuwandu hwezvikamu zvakapfava, zvinonzi monomers; nepo kusanganiswa kweizvi zvinobatsirwa nekudyidzana kwemakemikari kunopa mapolymers.

Chii chinonzi polymers?

Mapolymers anogadzirwa nekubatana kwemazana ezviuru zvemamorekuru madiki anonzi monometers anoumba maketani akasiyana siyana.

Plastics Classification:

• Plastics inokamurwa zvichienderana nemaitiro akasiyana, zvichibva pane:
• Polymerization nzira. (polymerization, polycondensation, polyaddition).
• Polymer chimiro. (crystallinity, superstructures).

Maitiro / zvimiro zvepolymer. (Zvinhu, mapurasitiki ehunyanzvi, mapurasitiki anoshanda akakwira).

Zvichienderana nezviri pamusoro, mapurasitiki akaiswa mu:

• Thermoplastics. (Polyolefins, Vinyl kana Acrylic Polymers, Polyamides, Polyesters, nezvimwewo)
• Thermostable.
• Elastomers.

Iyo mechanic zvinhu zve thermoplastic zvinhu zvine hukama neDegree yePolymerization, inova huwandu hunoyera huwandu hwezvibatanidza zvinoumba molecular cheni. Muchokwadi, iyo yakakwira dhigirii yepolymerization, iyo yakakwira viscosity, iyo yakakura kusimba uye kubvarura kuramba, kukura kuomarara, kunowedzera kusimba kwekupikisa uye, ukuwo, kushomeka kwekuita kristaro, kushoma kuzvimba uye kushomeka kutsemuka. .

Panyaya yeElastomeric uye Thermoset zvinhu, zvivakwa zvavo zvakagadziriswa neDegree yeCrosslinking, iyo inoyera chikamu chepakati pemapoinzi ekuyambuka (kubatana pakati pemamorekuru) mupolymer system. Iyo yakakwirira iyo dhigirii yekuyambuka, iyo yakakura kushorwa kwezvinhu, kuomarara kwayo uye kupikisa kwayo kupisa.

Mapurasitiki akareruka, anogona kuumbwa zviri nyore, anopa zvinhu zvakanaka chaizvo zvemuviri uye zvemagetsi, anogona kugadzirwa nemavara akasiyana, anogona kusanganiswa nemamwe mapurasitiki kana nezvinhu zvemukati, ane yakaderera mwero wekupisa uye magetsi conductivity, inonyatso pikisa kumakemikari, inopindika, inogona kushandiswa zvakare uye / kana kushandiswazve.

Kuti uwane zvakawanda nezve zvakakosha zve epurasitiki kuumba jekiseni muitiro yekugadzira chikamu chepurasitiki, unogona kushanya kuDjmolding pa https://www.djmolding.com/description-of-the-plastic-injection-molding-method-and-manufacturing-process-step-by-step/ nokuti zvimwe info.
