Kupanga ndondomeko ya PP yolumikizidwa

Thumba lonyowa Kodi zopangidwa ndi polypropylene ule ndi polyethylene ule ngati zinthu zazikuluzikulu, zotayika ndikudulidwa mu waya wabwinja, kenako ndikuwumbidwa ndikusungidwa. Matumba otakata omwe tiyenera kuti tawonera, koma kodi ukudziwa? Apa, tiyeni tiwone.

Mbiri Yachikwama

Mu 1930s, H. Janeque adapanga ukadaulo watsopano wopanga mafilimu odulira (mafilimu) ndikugawa ulusi wafilimuyo kudzera mu kanema wa polyvinyl chloride.

Mu 1950s, o. B. Rasmusse adadwala ulusi wokutira pogwiritsa ntchito njira zopitilira mafilimu komanso zida zotambasuka.

Mu 1965, Europe inayamba kupanga mafakitale osavala ayamwa zopangidwa ndi matumba opangidwa kuti apangidwe matumba a mafakitale.

Njira ya PP LINV  

Makina a PP TOVOND TOVV akuphatikiza: Kuwumitsa chosakanizira, makina ojambula, makina oyenda, makina ozungulira, makina odulira thumba.

1. Zolemba

 

Malinga ndi zomwe makasitomala amafuna kuti agwiritse ntchito bwino, magawo osiyanasiyana a zinthu zopangira amatha kugwiritsidwa ntchito. Ngati ndi chakudya, kugwiritsa ntchito zinthu zobwezeretsanso sikuloledwa, ndipo kuli koyenera kuwonjezera 8% ya masterbatch. Mwambiri, wokulirapo wa 30-40% ya zinthu zobwezerezedwanso ziyenera kuwonjezeredwa. Filler Masterbatch iyenera kuwonjezeredwa pa 10-15%.

2. Kujambula

 

Ili ndi gawo lomwe lauthwa la Polypropylene limakopeka ndi waya wabwino, m'lifupi mwake lomwe limatsimikiziridwa ndi kachulukidwe ka thumba la nsalu yolonjezedwa ndi kasitomala. Nthawi zambiri, m'lifupi mwake wa filimuyo ili pakati pa 10 ndi 15 mafilimu.

3.Nsalu yoluka

 

Yarn yakokedwa ndi yopangidwa ndi nsalu polowerera nyemba ndi weft, sitepe yomwe nthawi zambiri imachitika kuzungulira kozungulira. Pamaso pankhondo yankhondo isanalowe m'makina ozungulira, ulusi wanthete umawoloka pogwiritsa ntchito mawonekedwe a bulauni, ndipo weff bobbin imasunthira mozungulira kudzera mu silinda. Chiwerengero cha ma arp arp kulowa makina ozungulira amadziwika ndi kuchuluka kwa makina ozungulira.

Mu zoterezi, pali zizindikiro zingapo: zotupa, kutalika, mphamvu zambiri ndi kulemera kulikonse kwa nsalu yolukayo.

4. Makanema okutira

 

Gawo ili limakhudza njira yolumikizirana kapena yokutidwa ndi nsalu yolukidwayo, zokutira ndi pepala kapena kanema kuti mupange silinda kapena nsalu. Nsalu ya crinder imatha kudulidwa, kusindikizidwa ndikumangiriridwa kuti apange zikwama wamba, kapena zozikika, zopindika, kudula ndikumangiriridwa kupanga zikwama za simenti.

5. Kusindikiza ndi kudula   

 

Chovala choyenererachi chidzasindikizidwa pa nsalu yolumikizidwa ndi mankhwala okhudzana ndi makina osindikizira, kenako makina odulira thumba (makina odulira) amadula kasitomala.   

6. kusoka

 

Nsalu yodulidwa yodulidwa imapangidwa mu thumba lonyowa la PP ndi makina osoka a thumba.

Mu dziko la National GB / T8946, katundu wa Tnsile kulowera kumphepete mwa mtsinjewo ndipo msoko umafotokozedwa. Zinthu zazikulu zomwe zimakhudza mphamvu za kusunthira ndi mitundu yosiyanasiyana yozungulira, kukula kwa mtunda, kukula, kukula kwa mtunda kapena njira yodulira m'mphepete, njira yodulira, etc.

Zisonyezo zaluso za njira yoluka  

 

  1. Kuchulukitsa   

Kuchulukitsa koloka kumatanthauza kuchuluka kwa chiwerengero cha arp ndi weft x 100mm chotupa. Miyezo ya National imafotokoza kuchuluka kwa kansalu kachulukidwe kanu, kansalu kanu kowoneka ngati 36 × 36 / 10cm, 40 × 48 / 10cm.

 

  1. Khalidwe lililonse la gawo la nsalu yolumikizidwa   

Kulemera pa malo a nsalu yolumikizidwa kumafotokozedwa mzigawo wa buramu, komwe ndi chizindikiro chofunikira kwa kansalu ka thonje. Mbali ya mita imodzi imakhala ndi mita imatengera chipata chantheka ndi kupindika kwa waya komanso makulidwe owoneka bwino, omwe amakhudza mphamvu ya ophatikizika ndipo ndi gawo lalikulu la chiwongolero cha wopanga.  

 

  1. Chovala choluka   

Pa nsalu yosoka, imatha kupirira ntchentche ndi weft pa mbali ziwiri za katundu wa tunsile, atero anderp, weft tansile.  

 

  1. M'mbali   

Chovala chosiyanasiyana cha utoto chimakhudza mwachindunji njira yopangira chikwama. Chifukwa cha nsalu za cylinder, m'lifupi mwake chimawonetsedwa ndi khwalala; Nyama yokulungidwa ndiyofanana ndi theka la kuzungulira.  

 

  1. Wamansa  

PP Flat Chovala chokazinga amamva kukula, lofananira, ndi lopindika;

Nsalu yotsekedwa ya silika yotsekedwa ndi yofewa, yofufuta mafuta osati yowuma;

Kuphatikiza kwa calcium Godbatch kupita ku PP Flat Yarn kumamumva bwino; Kuphatikiza kwa HDPE PRPE ku PP kumapangitsa kuti ikhale yofewa.

Ngati chofunda chathyathyathya ndi chopapatiza, choluka chikhala chosalala komanso chofewa kukhudza; Ngati chofunda chathyathyathyathya ndi chachikulu, chotupa chidzakhuta zambiri komanso kumverera kovuta.  

 

Popangathumba lonyowa, Chiwerengero cha zinthu zopangira ndikuwonetsetsa kuti malonda amayamba, makamaka pankhani ya zakudya, zida zopangira sizingawonjezere zida zobwezerezedwanso; Kujambula ndi kulumikizana kovuta kwambiri; Kuluka, kusindikiza ndi kusoka ndi chitsimikizo chofunikira cha zopatsa thanzi, makamaka pazinthu za chakudya, zofunikira zosindikiza ndizokwera.  

 

Pazopanga yonse yopanga, magawo aluso ndi zizindikiro za njira iliyonse amakhala ndi ulalo wachindunji pazogulitsa. Kafukufuku wokhudza mphamvu iliyonse yaukadaulo ndi chizindikiro cha malonda atha kulimbikitsa kupanga, onetsetsani kuti pabululime ndi kusintha mpikisano.
