Kodi matumba a tiyi ndi chiyani?

Kunena kuti pali mitundu ingapo ya zida za thumba la tiyi, zida zodziwika bwino za thumba la tiyi pamsika ndi ulusi wa chimanga, zinthu zosalukidwa pp, zinthu zosalukidwa ndi pet ndi pepala losefera, ndi

Matumba a tiyi a mapepala omwe aku Britain amamwa tsiku lililonse. Ndi chikwama cha tiyi chamtundu wanji chomwe chili chabwino? M'munsimu muli mawu oyamba a mitundu iyi ya matumba a tiyi.

1. Thumba la tiyi la chimanga
Ulusi wa chimanga ndi ulusi wopangidwa kuchokera ku chimanga, tirigu ndi zowuma zina monga zopangira, zomwe zimapangidwira mwapadera kukhala lactic acid kenako ndi polymerized ndi kupota. Ndi fiber yomwe imamaliza kufalikira kwachilengedwe ndipo imatha kuwonongeka. CHIKWANGWANI sichigwiritsa ntchito mafuta a petroleum ndi zinthu zina zopangira mankhwala konse, ndipo zinyalala zake zimatha kuwola kukhala mpweya woipa ndi madzi pansi pa zochita za tizilombo tating'onoting'ono m'nthaka ndi m'madzi am'nyanja, ndipo sizidzawononga chilengedwe.

2. Non-woven pp zinthu tiyi thumba
Ma pp ndi polypropylene, yomwe ndi polima yopanda chiseled, yopanda fungo, komanso yopanda kukoma yamkaka yoyera kwambiri. PP polyester ndi mtundu wa amorphous, malo ake osungunuka ayenera kukhala pamwamba pa 220, ndipo mawonekedwe ake otentha ayenera kukhala pafupifupi madigiri 121. Koma chifukwa ndi macromolecular polima pambuyo pa zonse, kutentha kwapamwamba, kumachepetsa kusanthula
Kuthekera kwakukulu kwa oligomers, ndipo zambiri mwazinthuzi sizabwino paumoyo wamunthu. Kuphatikiza apo, malinga ndi momwe kasitomala amagwiritsira ntchito, madzi otentha nthawi zambiri amakhala madigiri 100, kotero makapu apulasitiki ambiri sakhala ndi madigiri opitilira 100.

3. Thumba la tiyi losalukidwa ndi ziweto
Monga zida zonyamula, PET ili ndi kukana kwapamwamba komanso kutsika kwa kutentha. Ikhoza kugwiritsidwa ntchito kwa nthawi yaitali mu kutentha kwa madigiri 120, ndipo imatha kupirira kutentha kwa madigiri 150 kwa nthawi yochepa. The permeability wa mpweya ndi nthunzi wa madzi ndi otsika, ndipo ali ndi mpweya wabwino, madzi, mafuta ndi fungo lachilendo kukana. Kuwonekera kwapamwamba komanso gloss yabwino. Ndiwopanda poizoni, wosakoma, ndipo uli ndi ukhondo ndi chitetezo, ndipo ukhoza kugwiritsidwa ntchito mwachindunji muzakudya.

4. Matumba a tiyi opangidwa ndi pepala losefera
Kuphatikiza pa pepala losefera lomwe limagwiritsidwa ntchito m'ma laboratories wamba, pali ntchito zambiri za pepala losefera m'moyo watsiku ndi tsiku, ndipo pepala losefera khofi ndi amodzi mwa iwo. Pepala la fyuluta pamtunda wakunja wa thumba la tiyi limapereka kufewa kwakukulu ndi mphamvu yonyowa. Mapepala ambiri osefera amapangidwa ndi ulusi wa thonje, ndipo pali mabowo ang'onoang'ono osawerengeka pamwamba pake kuti tinthu tamadzimadzi tidutse, pomwe tinthu tating'onoting'ono tokulirapo sitinatchulidwe.

5. Matumba a tiyi a mapepala
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito m'thumba la tiyi la pepalali ndi abaca. Izi ndi zoonda komanso zimakhala ndi ulusi wautali. Mapepala opangidwa ndi amphamvu komanso otsekemera, omwe amapanga mikhalidwe yoyenera kufalitsa kukoma kwa tiyi. Zina zopangira ndi pulasitiki yotsekera kutentha, yomwe imathandizira kusindikiza thumba la tiyi. Pulasitiki imeneyi siyamba kusungunuka mpaka itatenthedwa kufika 160°C, choncho sikophweka kumwazikana m’madzi. Pofuna kuteteza thumba la tiyi lokha kuti lisasungunuke m'madzi, chinthu chachitatu, zamkati zamatabwa, zimawonjezeredwa. Pambuyo pa kutsanulidwa kwa abaca ndi pulasitiki, kunakutidwa ndi matabwa a matabwa, ndipo potsirizira pake anayika mu makina akuluakulu a mapepala aatali mamita 40, ndipo pepala la thumba la tiyi linabadwa.
