Igikorwa cyo gukora cya PP

PP Nibicuruzwa bikozwe muri polypropylene na polyethylene resin nkibikoresho nyamukuru byibanze, byaragaragaye kandi birambuye muri wire iringaniye, noneho bikozwe kandi bikozwe. Imifuka iboshye Tugomba kuba yarabonye, ​​ariko uzi inzira yacyo? Hano, reka tubimenye.

Amateka yumufuka ubo

Mu myaka ya za 1930, H. Jaeque yahimbye ikoranabuhanga rishya ryo gutunganya filaments (firigo) no kugabana fibre fibre binyuze mu bushakashatsi burambuye bwa firime ya Polyviny;

Mu myaka ya za 1950, O. B. Rasmusse yarangije kuharanira gukoresha uburyo bwo kwirinda film hamwe nibikoresho birambuye.

Mu 1965, Uburayi bwatangiye umusaruro w'inganda kavumburwa neza ku buryo bwo kutarangiza umusaruro w'imifuka iboshye mu gupakira inganda.

PP iboteye igikapu  

Imashini ikoresha imifuka ya PP ikubiyemo: Kuma Mixer, gushushanya imashini, imashini igabanya, imashini ibobora imashini, icapiro izenguruka, imashini yo gucapa, imashini idoti.

1. Ibikoresho bya gake

 

Ukurikije ibisabwa byabakiriya kubipimo byiza, bitandukanye byibikoresho fatizo birashobora gukoreshwa. Niba ari ibiryo, gukoresha ibikoresho byatunganijwe ntibyemewe, kandi birakwiye kongeraho bitarenze 8% byungurura. Muri rusange, ntarengwa ya 30-40% yibikoresho byatunganijwe bigomba kongerwaho. Filler SETBATCTCTCTCH igomba kongerwaho kuwa 10-15%.

2. Gushushanya

 

Iyi ni intambwe aho polypropylene yashizwemo insinga nziza, ubugari bwihariye bwa bigenwa nubucucike bwimifuka iboshye isabwa numukiriya. Muri rusange, ubugari bwa filament buri hagati ya filice 10 na 15.

3.Umwenda uboshye

 

Umudozi arakururwa kandi ikozwe mu mwenda uhuza intambara no kwiba, intambwe isanzwe ikorwa ku mpeshyi. Mbere yuko imyenda ya Warp yinjira mu imashini iboshye, yambaye ubusa yambutse hakoreshejwe icyerekezo cyijimye binyuze mu gufungura imyenda yambutse kugirango abohoze imyenda muri silinderi. Umubare wintambara winjira winjiza imashini ibogamye izenguruka igenwa numubare wa shitingi mumashini irengerwa.

Muriyi mikorere, hari ibipimo byinshi: Kuboha ubucucike, ubugari, imbaraga zidasanzwe nuburemere kuri buri gice cyambaye imyenda iboheye.

4. Guhinga firime

 

Iyi ntambwe ikubiyemo amatara cyangwa gutwika umwenda uboshye, ibikoresho byo gutwikira hamwe nimpapuro cyangwa firime kugirango utange silinderi cyangwa urupapuro rwabigenewe. Igitambara cya kilinder gishobora gucibwa, cyacapwe kandi gidoda kugirango gikore imifuka isanzwe yo hasi, cyangwa igacanwa, ikato, yagabanijwe kandi idoze gukora imifuka ya sima.

5. Gucapa no gukata   

 

Igitambaro cyujuje ibyangombwa bizacapurwa kumyenda iboheye hamwe namashusho ajyanye no gucapa mashini, hanyuma imashini yo gukata umufuka (gukata imashini) izagabanya kugirango ihuze nubunini bwabakiriya.   

6. Kudoda

 

Igitambaro cyaciwe kikozwe muri PP ikozwe mu gikapu cyo kudoda igikapu.

Muri GB / T8946, umutwaro wa Tensile mu cyerekezo cya Seam Erge na Seam Hasi. Ibintu nyamukuru bireba imbaraga zumudozi nuburyo butandukanye bwumurongo, ubunini bwintera yo kudoda, ubunini bwintambwe, ubunini bwumufuka udoda, nibindi.

Ibipimo bya tekiniki byerekana inzira yo kuboha  

 

  1. Ubucucike   

Ubucucike buboshye bivuga umubare wintambara nubudodo muri 100mm X 100mm Chemcric. Ibipimo by'igihugu byerekana ubucucike n'ubucucike bwo kwihanganira imyenda iboherwa, bikunze gukoreshwa imyenda y'imyenda iboherwa ni 36 / 10cm, 40 × 40/5

 

  1. Ubwiza kuri buri gice cyambaye imyenda iboheye   

Uburemere buri gice cyimyenda iboherwa bugaragazwa na metero kare yinzabibu, nikimenyetso cyingenzi cya tekiniki cyigitambara kiboheye. Gramboge kuri metero kare cyane cyane biterwa no gucuranga no gukundwa n'ubwinshi bw'insinga za tensile n'ubushobozi bw'imyenda iboshye kandi ni igice kinini cyo kugenzura ibiciro ku wakora.  

 

  1. Umutwaro wa Tensile   

Mugituba cyaravuze ko kumyenda iboshye, irashobora kwihanganira intambara no gukubita icyerekezo byombi byumutwaro wa Tensile.  

 

  1. Ubugari   

Ubugari bwibitambaro bifatika bigira ingaruka muburyo bwo gukora imifuka. Ku mwenda wa silinderi, ubugari bwerekanwe na tch yijimye; Intambara yiziritse ihwanye na kimwe cya kabiri cyuzengurutse.  

 

  1. Umubyindi  

Pp flak ingurube iboheye imyenda yunvikana, yagutse, coarser na stiffer;

HDPE Flat Flat Imyenda yoroshye, irahiga ntabwo ari nyinshi;

Hiyongereyeho Malcium Masterbatch kuri pp flathnish yumva ushikamye; hiyongereyeho hdpe nto kuri pp ituma byoroshye.

Niba filament iringaniye rifunganye, ibohe zizaba igorofa kandi yoroshye gukoraho; Niba filament iringaniye ari yagutse, ababo quave bazagira filaments nyinshi kandi bumva.  

 

Mu buryo bwo gukora umusaruro waPP, Igipimo cyibikoresho fatizo ni ukureba ko ibicuruzwa byujuje ibicuruzwa, cyane cyane iyo bigeze ku bicuruzwa byibiribwa, ibikoresho fatizo ntibishobora kongeramo ibikoresho byatunganijwe; gushushanya ni ihuriro rikomeye; Kuboha, gucapa no kudoda ni garanti yingenzi yibicuruzwa Byizamuro, cyane cyane kubicuruzwa byibiribwa, ibisabwa byo gucapura biri hejuru.  

 

Mubikorwa byose byumusaruro, ibipimo bya tekiniki nibipimo bya buri nzira bifite umurongo utaziguye ku ngaruka zubwiza bwibicuruzwa. Kwiga ingaruka kuri buri kigereranyo cya tekiniki nigipimo cyerekana ubuziranenge bwibicuruzwa birashobora guteza imbere umusaruro, menya neza ibicuruzwa no kuzamura irushanwa ryibigo.
