The production standards for degradable particles mainly include the following aspects:

原料選擇：生產(chǎn)可降解顆粒需要選擇符合相關(guān)標(biāo)準(zhǔn)的可降解材料，如淀粉、聚乳酸（PLA）、聚羥基脂肪酸酯（PHA）等。這些原料應(yīng)該符合和行業(yè)的相關(guān)標(biāo)準(zhǔn)要求，確保其可降解性能和對環(huán)境的友好性。

Raw material selection: To produce biodegradable particles, it is necessary to choose biodegradable materials that meet relevant standards, such as starch, polylactic acid (PLA), polyhydroxyfatty acid ester (PHA), etc. These raw materials should comply with relevant national and industry standards to ensure their degradability and environmental friendliness.

生產(chǎn)工藝控制：生產(chǎn)可降解顆粒需要嚴(yán)格控制生產(chǎn)工藝，確保產(chǎn)品的質(zhì)量和性能穩(wěn)定。包括原料配比、加工溫度、擠出速度、熔體流動性等參數(shù)的控制，以及后續(xù)的冷卻、切割和包裝等環(huán)節(jié)的控制。

Production process control: The production of degradable particles requires strict control of the production process to ensure stable product quality and performance. This includes the control of raw material ratio, processing temperature, extrusion speed, melt fluidity and other parameters, as well as the subsequent control of cooling, cutting, and packaging processes.

物理性能測試：生產(chǎn)的可降解顆粒需要進(jìn)行一系列的物理性能測試，來評估其在使用和分解過程中的性能表現(xiàn)。常見的測試項目包括顆粒的密度、流動性、抗拉強度、熔融指數(shù)等。

Physical performance testing: The produced biodegradable particles require a series of physical performance tests to evaluate their performance during use and decomposition. Common test items include particle density, fluidity, tensile strength, Melt flow index, etc.

可降解性能測試：可降解顆粒的可降解性能也是生產(chǎn)標(biāo)準(zhǔn)中關(guān)注的。通過模擬真實的環(huán)境條件，如土壤、水體等，評估顆粒在一定時間內(nèi)的降解情況。常見的測試項目包括降解速率、降解產(chǎn)物分析等。

Degradability testing: The degradability of degradable particles is also a focus of attention in production standards. Evaluate the degradation of particles over a certain period of time by simulating real environmental conditions such as soil and water. Common testing items include degradation rate, analysis of degradation products, etc.

環(huán)境標(biāo)準(zhǔn)要求：生產(chǎn)可降解顆粒需要符合和地方相關(guān)的環(huán)保要求。包括廢水、廢氣的排放標(biāo)準(zhǔn)，以及固體廢棄物的處理要求等。

Environmental standard requirements: The production of degradable particles needs to comply with relevant national and local environmental requirements. This includes emission standards for wastewater and exhaust gas, as well as requirements for the treatment of solid waste.

總之，生產(chǎn)可降解顆粒需要從原料選擇、生產(chǎn)工藝控制、物理性能測試、可降解性能測試和環(huán)境標(biāo)準(zhǔn)等多個方面進(jìn)行嚴(yán)格控制，以確保產(chǎn)品的質(zhì)量和符合環(huán)保要求。這些標(biāo)準(zhǔn)要求的實施和監(jiān)管有助于推動可降解顆粒產(chǎn)業(yè)的健康發(fā)展。

In summary, the production of degradable particles requires strict control from multiple aspects such as raw material selection, production process control, physical performance testing, degradability testing, and environmental standards to ensure product quality and compliance with environmental requirements. The implementation and regulation of these standard requirements can help promote the healthy development of the degradable particle industry.
