Twine udzu twine: makhalidwe, ntchito

Ulimi wamakono ndi wovuta kulingalira popanda kuchuluka kwa mitundu yonse ya makina ndi magulu. Amathandizira kwambiri ntchito ndipo nthawi zina amawathandiza kuti azigwira ntchito. Makampani onse akupanga zopereka zina zowonjezera makina, monga fodya wa twine. Popanda izo, kukonzekera kutentha (udzu, udzu, haylage) sizingatheke.

Twine

Mawu akuti spaghetto amatembenuzidwa kuchokera ku Italy monga "chingwe chochepa". Kufupikitsidwa spago - "twine" kapena "twine".

Ndi ulusi woonda kwambiri. Zitha kukhala zosiyana-siyana kapena zosakanizidwa. Zojambula zambiri - zowonongeka kapena zopotoka za zingwe zingapo. Ndipo kupotoza kumachitika mosiyana ndi kulemekeza kupotoka kwa fiber yoyamba. Izi zimathandizira kukwaniritsa mphamvu yowonjezera. Twine polypropylene udzu wosakanizidwa ukhoza kupangidwa kuchokera ku utsi wosasunthika.

Mitundu

M'magulu osiyanasiyana a zochita za anthu sangathe kuchita popanda chingwe. Pomwe pali ulusi wopangira, kwinakwake pamafunika chirengedwe. Malingana ndi zinthu zomwe zimagwiritsidwa ntchito popanga chingwe, zimagawidwa m'mitundu yambiri. Asanayambe kupanga zipangizo (polypropylene) twine, chingwe chinapangidwira zokhazokha zachilengedwe. Iwo akhoza kukhala:

• thonje;

• Lineni;

• jute;

• hemp;

• lnopenkovye;

• Sisal;

• pepala;

• polypropylene;

• Polyamide.

Nsalu zamakono ndizopindulitsa pa mtengo ndi kupirira. Koma palinso malo ena omwe sitingathe kuchita popanda tine kuchokera kuzinthu zachilengedwe - makampani ogulitsa. Zonse zopangira kusuta zimangokhala ndi jute wachibadwa. Izi zimagwiritsidwanso ntchito osati nyama, komanso nsomba.

Zizindikiro za thupi

Tini udzu twine uyenera kukhala wolimba mokwanira kuti upirire mtolo umene unaperekedwa pa iwo. Pali zizindikiro zingapo zomwe zida zakuthupi zimatsimikiziridwa:

• Kulingalira kwapadera ("tex" mu Latin kuchokera ku "weave"). Chizindikiro ichi chimayesa kuyeza kulemera kwake. Ngati twine 2200 TEX, zikutanthauza kuti makilomita 1 a ulusiwo amalemera 2200 magalamu (2.2 kg). Unit of measure ndi g / km.

• Sulani mphamvu. Amayesedwa mu kilogalamu ndipo amatha kuthekera kwa zinthu zomwe zingathe kupirira kupsinjika maganizo. Zimapezeka mosavuta pamene zimamangiriza bale. Mwachitsanzo, ngati TEX ndi 2500g / km, ndiye kuti mphamvu ya phokoso ili pafupifupi makilogalamu 100.

• Mphamvu ya misozi ya nsalu. Ulusi wokha uli wamphamvu kwambiri kuposa nsalu yolemetsa. Kukhoza kwake kulimbana ndi katundu kumagwa kawiri. Twine TEX 2500 g / km: kulimbikitsani kuti muphwanyidwe bwino - pafupifupi makilogalamu 50.

• Kutsutsana ndi mazira a ultraviolet (UV). Zinthu zachilengedwe zakunja zingakhudze zinthu. Tsamba udzu wa twine umalowa m'thupi ndi momwe zimakhudzidwira tikamagwiritsa ntchito mpweya ndi ultraviolet. Izi zimachitika pa nthawi yosungirako nsalu.

Zinthu zazikulu zomwe zimakhudza chitetezo cha ulusi:

• kutentha kutentha;

• kuchulukitsa;

• Kukaniza kuswa (kuyanika);

• Kukhalapo kwazitsulo (zochokera ku UV);

• mtundu wa fiber (gwero).

Zamakono zamakina zamakono zimakulolani kuti musankhe mayendedwe abwino omwe ali ndi zowonjezera zowonjezera kuti muteteze chiwopsezo ku chiwonongeko.

Chiwerengero cha ntchito

Mu moyo wathu wa tsiku ndi tsiku pali malo okwanira omwe sitingathe kuchita popanda chinthu chophweka ngati twine (chingwe). Mitengo yonse yokolola udzu mu ulimi imasowa makina ndi ulusi wapamwamba. Popanda izo, kubzala ng'ombe sikungatheke. Kutentha kwakukulu kumatulutsidwa ndipo kumagwiritsidwa ntchito mosungirako nyengo yachisanu chifukwa cha chingwe cha kusinja.

Mu ulimi, amagwiritsidwa ntchito ku minda ya mpesa ndi zomera. Monga mapepala apangidwe akhala akugwiritsidwa ntchito kwa zaka zoposa zana limodzi. Okonza zamakono angathe kupeza mosavuta ntchito mkati. Ngakhale abale athu ang'onoang'ono amagwiritsa ntchito chingwe cha hemp. Sitima zamakono zamakono sizikhoza kuchita popanda zingwe zopindika. Nsonga ya polypropylene ndi yofunikira popanga nsomba.

Polypropylene mankhwala

Chodziwika kwambiri ndi udzu wa polypropylene twine. Mtengo wa bobini ukhoza kusiyana pakati pa madola 10-50 US. Zimadalira mtundu, kulemera ndi khalidwe la mankhwala operekedwa. Zopindulitsa zake zazikulu ndi izi:

• Sizitentha kuchokera ku chinyezi;

• Sizowola;

• kusagwirizana ndi kusintha kwa kutentha;

• amatsutsana mobwerezabwereza kugwedeza;

• samachita magetsi;

• otchipa kusiyana ndi anzawo kuchokera ku zipangizo zachilengedwe;

• Kufewa kwa zinthuzi kungagwiritsidwe ntchito mu njira ndipamwamba zowonongeka;

• amphamvu, mukhoza kuyimitsa bales kwambiri.

Kupanga

Ulusi wopangira zinthu ndi wotchipa kusiyana ndi zachirengedwe. Amatha kupatsidwa chithandizo chamankhwala osiyanasiyana, kuwonjezera zofunikira zowonjezera, kufunafuna kusintha kwa izi kapena zina.

Twine polypropylene udzu wosakanizika amapangidwa ndi granules yapadera ya polypropylene. Ndondomeko yokha ikhoza kufotokozedwa motere: granules imalowa mu hopper yapadera kuti ikhale yofewa. Icho chimakakamizidwa kuchoka mwa icho kupyolera mutu wopangidwa. Mafilimuwo amachotsedwa, otambasulidwa ndikudulidwa kukhala zochepa. Mu chipinda chapadera cha kayendetsedwe ka kotenga nthawi, amapeza mankhwala awo ndi zakuthupi ndipo ali okonzekera kupotoza. Ndiye iwo ali ndi zilonda pazinthu.

Mtundu wa mankhwalawo umadalira pa zifukwa zingapo:

• kupanga zida;

• chikhalidwe cha kutentha; Ngati teknoloji sichiwonetsedwe, ma macromolecule amawonongeka ndipo kusungunuka kumene kumakhala kosavomerezeka kumapezeka;

• Kukhazikika kwa kupanikizika kwakukulu, kusakhazikika kumabweretsa mavuto osavuta.

Opanga amapindula kuchepa kwa mitsempha yeniyeni, komanso kuwonjezeka kwa mphamvu zamagetsi. Zochitika zam'tsogolo zimakhala ndi mphamvu yamphamvu ndi yofewa. Izi ndizofunikira kwambiri pakumangiriza mawanga, ndi odalirika komanso odalirika.

Odziwika otchuka kwambiri mpaka pano ndi China, United States, Turkey. Kuchokera kumayiko a Kumadzulo kwa Ulaya - Finland (Piippo), Austria (TEWE), Portugal (Cordex), Hungary (Tama Twine), Czech Republic (JUTA). Pambuyo pa Soviet malo, twine kulumikiza twine amapangidwa ndi makampani Ukraine "Polimerspagat", ku Belarus - "Khimvolokno-Belaruskolokno", ku Russia - "Kamenskvolokno".
